Planning A Dynamodb...### Scaling bottlenecks and hot partitions Although DynamoDB is built to scale horizontally, its internal limits hinder certain access patterns. By design, each DynamoDB partition is limited to about 3,000 read capacity units and 1,000 write units per second. This means if a single partition key (i.e., a “hot key”) receives excessive traffic, it can throttle, a phenomenon known as the hot partition problem. Applications with uneven data access or extremely high update rates to a small set of keys may hit these ceilings. Additionally, DynamoDB items are capped at 400 KB in size, so applications needing to store larger objects or blobs per record cannot do so directly. There are workarounds, such as splitting data across items or using S3 for overflow, but they are more complex. Finally, DynamoDB’s 1 MB limit per Query/Scan page can make analytical scans or large result sets cumbersome to retrieve without pagination. When such limitations start affecting development by needing to design around item size or partition throughput, some teams opt for databases with fewer constraints. ### Operational complexity and ecosystem fit DynamoDB is operationally simple within AWS, but that strength can turn into a weakness if your company uses other cloud service providers. As an AWS-only service, DynamoDB locks you into the AWS ecosystem, which can be a problem for multi-cloud or on-premises strategies. Organizations that want cloud provider independence or need to deploy in their own data centers for data sovereignty or latency reasons cannot use DynamoDB in those environments. Additionally, some teams find DynamoDB’s integration model too limiting. For example, it doesn’t support many complex queries nor stored procedures, and it requires AWS-specific tooling such as CloudWatch for monitoring, which makes it more difficult to build a custom monitoring pipeline via OpenTelemetry, Prometheus, or DataDog. Similarly, Amazon DynamoDB doesn't have database-level user management, and it does not manage users or passwords directly. Instead, it relies on the broader AWS ecosystem to authenticate users and applications securely, so it handles authentication primarily through AWS Identity and Access Management (IAM). … ### Feature limitations and data model mismatches As applications evolve, they may need capabilities that DynamoDB doesn’t have or doesn’t do well. DynamoDB is schemaless and supports ACID transactions, but it lacks the rich querying and JOINs of relational databases or some NewSQL/NoSQL peers. Another example is global data consistency: DynamoDB’s global tables offer multi-region replication, but only with eventual consistency, meaning that writes are eventually propagated. It cannot do multi-region strong consistency, which is a deal-breaker for financial or compliance uses that require up-to-date reads across regions. Additionally, DynamoDB’s secondary indexes are useful but have constraints, such as at most 20 global secondary indexes (GSI) per table, which must be defined up front, and some query patterns are hard to implement. If an application starts needing ad hoc queries, full-text search, graph traversals, or other features, one must either supplement DynamoDB with other services or migrate to a database that natively supports those queries. In short, evolving requirements for stronger consistency and richer queries can lead teams to look for a product with those functions. … ### Throughput and hot-key limits DynamoDB partitions have a finite throughput limit of approximately 3,000 RCUs and 1,000 WCUs per partition by default. If your access pattern can’t be evenly distributed, such as if one customer or one item ID is extremely popular, you risk hitting throttling on that partition. Solutions include careful data modeling to distribute hot keys or using DynamoDB’s adaptive capacity, but these may not fully eliminate hot spots. ### Latency profiles DynamoDB latency can run from under 10 milliseconds to tens of milliseconds. Under heavy load, latencies can spike if the table is throttling or if cross-region replication is involved. If your application demands consistent sub-5ms or sub-1ms latency, you’ll likely need in-memory or highly optimized databases. Aerospike, for instance, uses a smart client that interacts with the node holding the data, often with <1ms read latencies for local queries. … ### Query and data model differences DynamoDB requires careful upfront data modeling by designing primary keys and secondary indexes to satisfy known query patterns because it does not support ad hoc queries or joins. If teams find this too restrictive and need to do full table scans for certain queries or struggle with the 20 index per table limit, a new database might offer more flexibility.

DynamoDB Considered Harmful### 1. It's inflexibility will slow you down. Initially, DynamoDB's speed and schema-less nature can make development fast. Although DynamoDB isn't modelled around schema's (like a traditional SQL database), it is modelled around queries. This means you need to know the query model up front. In a mature product, you might have a good idea of what possible queries you would want but in a greenfield product it's downright impossible. But, regardless of how mature your product is we all suffer from a fog of war. It's impossible to know what feature requests will be fired at us by a product manager. This is where DynamoDB will start to become as cumbersome as jeans in a rainstorm. Because you originally modelled the database around the queries you knew about, it becomes inflexible to change for the new queries you need to perform. Often times, teams just add new global secondary indexes (which behind the scenes is a complete copy of your database). But these are limited to 20 per table. And it creates another problem, deciding what index to use when. This becomes a headache to maintain and build upon. Some may reason that they can create other tables around the new query model, or change the existing database. … ### 4. It's challenging to work on your system locally Working with DynamoDB locally isn't as simple as running a docker container (like ehem, MySQL or Postgres). So, then you're focused to have a "remote" development environment. Where you have resources deployed to the cloud that are used by each developer. These can work, but provide horrendous experiences. Changes to system configuration have to be deployed and you can't work offline. There are a whole host of problems that arise as a result of systems that cannot just be run on a computer.

When NOT To Use: DynamoDB - Sam Dhar#### 1. Query Limitations: Speed and Simplicity comes at a cost DynamoDB’s design prioritizes scalability and speed, but that focus comes at the expense of query flexibility: - **No Rich Queries**: Forget SQL-like joins, subqueries, or aggregations. DynamoDB is built for straightforward key-value lookups and range queries on secondary indexes. Anything more requires either preprocessing your data or building custom query logic in your application. - **Table Scans Are Expensive**: When your query doesn’t align perfectly with your table or index schema, DynamoDB resorts to scanning the entire table, leading to performance degradation and skyrocketing costs. **Why It Matters:** Applications with evolving or unpredictable query requirements will quickly hit a wall. Data architects often find themselves rewriting their models—or worse, re-architecting their entire application. #### 2. Rigid Data Size and Attribute Limits DynamoDB enforces tight constraints on what you can store: - **Item Size Limit**: Each item can only be 400 KB. Items exceeding the 400 KB size limit will result in a `ValidationException`. To handle large data, consider storing oversized objects in Amazon S3 with a reference in DynamoDB, splitting the data into smaller related items, or compressing large attributes to fit the limit. This creates additional dependencies, increasing both complexity and latency. - **Secondary Index Limitations**: Indexes inherit the same size limits as table items. If your data requires large or complex indexes, this constraint becomes a headache. **Why It Matters:** These restrictions can bottleneck feature development. Engineers may end up building brittle workarounds that add long-term maintenance overhead. … - **Hot Partitions**: DynamoDB's partition-based design can cause performance issues when specific partitions experience disproportionate traffic, creating "hotspots." These occur in scenarios like a celebrity's trending profile or a new album drop from a popular musician, where sudden surges in access exceed the throughput of individual partitions, leading to throttling, latency, or failures—even if overall capacity seems sufficient. … #### 4. Cost Spikes DynamoDB’s pricing model—based on provisioned or on-demand throughput—can be both a blessing and a curse: - **Unpredictable Costs**: Applications with variable workloads are particularly vulnerable to cost spikes, especially during traffic surges. - **Over-Provisioning Risks**: To avoid throttling, developers often over-provision read and write capacity, leading to wasted spend during off-peak times. **Why It Matters:** While DynamoDB can save money for workloads with predictable patterns, it’s a potential budget-killer for applications with spiky or unpredictable traffic. … - **Access Patterns First:** Access patterns play a crucial role in designing data models within DynamoDB. Unlike traditional SQL databases, where normalization is encouraged to reduce redundancy and enhance data integrity, DynamoDB necessitates a more pragmatic approach that focuses on the end-user query patterns. This often results in denormalization—where data is intentionally duplicated across multiple tables or records to optimize read performance. While such duplication can seem counterintuitive to those accustomed to relational database management systems (RDBMS), it aligns perfectly with DynamoDB’s philosophy of high availability and fast access. … - **Evolving Models Is Painful**: Once a data model is set, adapting to new access patterns can be time-consuming and error-prone, especially in applications with complex relationships or dynamic requirements. **Why It Matters:** Teams new to DynamoDB often struggle to adopt its "access-pattern-first" philosophy, leading to inefficient designs and wasted development effort. #### 6. Vendor Lock-In and Limited Deployment Options DynamoDB’s tight integration with AWS can be a double-edged sword: - **Proprietary Design**: DynamoDB’s architecture doesn’t translate easily to other databases. Migrating off DynamoDB often means rebuilding data models and rewriting substantial parts of the application. - **Cloud-Only**: DynamoDB doesn’t natively support on-premises or multi-cloud deployments. If you need to run workloads outside AWS, you’re out of luck. … #### 7. Lack of Built-In Observability Despite being a managed service, DynamoDB requires extensive monitoring to maintain performance and cost efficiency: - **No Out-of-the-Box Insights**: DynamoDB provides limited visibility into table usage and access patterns. You’ll likely need to integrate tools like CloudWatch or third-party monitoring solutions. - **Proactive Management Required**: Issues like hot partitions or throttling aren’t automatically resolved, leaving developers responsible for diagnosing and addressing them. **Why It Matters:** Monitoring DynamoDB effectively requires both expertise and additional tooling, countering the perception that it’s a completely "hands-off" service.
What do you dislike about Amazon DynamoDB? One downside of Amazon DynamoDB is that its pricing model can be difficult to predict, particularly with high or fluctuating workloads. If the database isn’t optimized properly, costs can rise quickly as usage scales. Also, the data model needs careful planning upfront, since it isn’t as flexible as traditional relational databases when you need complex queries or later schema changes. Review collected by and hosted on G2.com. … What do you dislike about Amazon DynamoDB? One thing I feel challenging in Amazon DynamoDB is that data modelling is not very straightforward for beginners. If the table design is not planned properly, it can cause performance issues later. Also, complex queries and joins are not supported like traditional relational databases. Sometimes cost can increase if read/write capacity is not configured properly. Initial learning curve is slightly high for new users. Review collected by and hosted on G2.com. … What do you dislike about Amazon DynamoDB? Data modeling requires careful upfront planning, and changes to access patterns can be difficult to accommodate later. Pricing can become complex and costly at scale if read and write capacity is not optimized. Debugging performance issues and understanding cost drivers can also be challenging compared to traditional relational databases. Review collected by and hosted on G2.com. … What do you dislike about Amazon DynamoDB? Below are the points which I dislike about DynamoDB:- 1. Limited Query Capabilities :- No joins and complex filtering 2. Cost Management Challenges :- If read and write operations are not optimized 3. Item Size Limit:- Max item supported is 400kB 4. Backup and Restore Costs Review collected by and hosted on G2.com. … What do you dislike about Amazon DynamoDB? The pricing is not transparent, and if the initial architecture is not set up correctly, it becomes very difficult to avoid scans which are very costly. Review collected by and hosted on G2.com. LP Luca P. Chief Operations Officer DEQUA Studio | Formerly CTO in MarTech … What do you dislike about Amazon DynamoDB? My main challenge with DynamoDB has been mastering its cost and performance optimization. While the pay-per-request model is incredibly flexible, it also means that you have to be vigilant. It’s easy for costs to escalate if you’re not careful about how you design your queries. … What do you dislike about Amazon DynamoDB? Pricing can become unpredictable with high workloads, especially with on-demand provisioning and data transfer costs. The learning curve is also steep for newcomers due to the wide variety of services and configuration options. Additionally, debugging or troubleshooting performance issues may require deep expertise or reliance on AWS support. Review collected by and hosted on G2.com. … What do you dislike about Amazon DynamoDB? EAWS databases can become expensive at scale, especially with high I/O or storage needs. Some services have complex pricing models and limits (like DynamoDB throughput). Also, vendor lock-in and limited customization compared to self-managed databases can be concerns for some users. Review collected by and hosted on G2.com.
3. **Pitfall: Misunderstanding Consistency Models.** - **Problem:** Not realizing that reads from GSIs and default table reads are eventually consistent. This can lead to stale data if an immediate read follows a write. - **Best Practice:** Understand the trade-offs. For reads that require absolute up-to-date data, use strongly consistent reads on the base table (doubles RCU cost). For GSIs, design your application to tolerate eventual consistency or implement read-after-write patterns with retries/delays if strong consistency is critical on GSI data. 4. **Pitfall: Over/Under-provisioning Capacity (Provisioned Mode).** - **Problem:** Setting RCUs/WCUs too low leads to throttling and errors. Setting them too high wastes money. - **Best Practice:** Monitor `Consumed*CapacityUnits` and `ThrottledRequests` metrics in CloudWatch. Implement DynamoDB Auto Scaling to adjust provisioned capacity automatically based on demand. Consider On-Demand mode if workloads are highly unpredictable. … - **Problem:** Applying relational database design principles (multiple normalized tables) directly to DynamoDB can lead to many tables and complex application-side joins, negating NoSQL benefits. - **Best Practice:** For simple use cases, separate tables are fine. For complex, related data, explore **Single Table Design (STD)**. This involves storing different but related entity types in a single table, using generic primary key attributes (e.g., `PK`, `SK`) and GSIs to model one-to-many and many-to-many relationships. This is an advanced topic but incredibly powerful.
1. **Query flexibility**: The query model is limited to primary keys and secondary indexes. Complex joins, aggregations and full‑text search require other services (e.g., Elasticsearch or Redshift). Secondary indexes increase cost and require careful design. 2. **Item size limit**: A single item cannot exceed**400 KB**, which is much smaller than document databases like MongoDB (16 MB) or Cassandra (2 GB). Large objects should be stored in S3 and referenced from DynamoDB. 3. **Partition throughput limits**: Hot partitions can occur if the partition key isn’t sufficiently distributed, leading to throttling and increased latency. 4. **Vendor lock‑in**: DynamoDB runs exclusively on AWS. Migrating to other clouds or on‑premises systems requires rewriting applications or using compatible services. … ### Specific Technical Limitations Don’t use DynamoDB if you require: - Stored procedures or triggers - Complex nested data (beyond 32 levels) - Immediate global consistency (global tables have ~1s lag) - Backups older than 35 days - Exactly-once CDC (change data capture) … ### The “Red Flags” Checklist **Reconsider DynamoDB if you answer yes to any:** - Need queries by more than 5 attribute combinations? - Items regularly exceed 100KB? - Monthly AWS bill must stay under $100? - Require JOINs across multiple tables? - Must run outside AWS? - Need ACID across tables? - Frequent analytical queries required? - Need full-text search?

DynamoDB 10 years latersalil999 on Jan 20, 2022 Engineering, however, was a disaster story. Code is horribly written and very few tests are maintained to make sure deployments go without issues. There was too much emphasis on deployment and getting fixes/features out over making sure it won't break anything else. It was a common scenario to release a new feature and put duct tape all around it to make sure it "works". And way too many operational issues. There are a lot of ways to break DynamoDB :) … Bulk loading data is the other gotcha I've run into. Had a beautiful use case for steady read performance of a batch dataset that was incredibly economical on Dynamo but the cost/time for loading the dataset into Dynamo was totally prohibitive. Basically Dynamo is great for constant read/write of very small, randomly distributed documents. Once you are out of thay zone things can hey dicey fast.

Why Amazon DynamoDB Isn't for EveryoneSo when you combine inexperienced devs, the lack of a clear plan for how to model a dataset in DynamoDB, and a managed database service that makes it really easy to ingest a lot of unstructured data — you can end up with a solution that spirals out of control even at a small scale. Lynn Langit, a cloud data consultant with experience in all three of the big public clouds, has seen enough of these botched implementations to be justifiably wary of businesses relying on NoSQL solutions like DynamoDB. … ### The Second Law of DynamoDB: At massive scale, DynamoDB’s usability is limited by its own simplicity. This is not a problem with the *architecture of Dynamo.* It’s a problem with what AWS has chosen to expose through the *service of DynamoDB*. At this point, we haven’t even touched on the issue of backups and restores — something DynamoDB doesn’t support natively and which gets awfully tricky at scale. The inability to back up 100TB of DynamoDB data was apparently a big reason why Timehop recently moved off the service altogether.

10 DynamoDB Advantages & Disadvantages [2026]## Disadvantages Of Using DynamoDB ### 1. Limited Querying Options Even though DynamoDB can store large amounts of data, querying data from within a DynamoDB database is tedious due to the limited querying options that the service provides. The service relies on the indexes for querying tasks and does not allow querying if no indexes are available. An alternative is to scan the entire table to query the data. However, this operation requires a significant amount of read capacity units, which becomes an expensive task once the database scales up. Additionally, complex queries involving multiple attributes can be challenging to implement. Developers often need to carefully design their data models and indexes upfront to ensure efficient querying. ### 2. Difficult To Predict Costs DynamoDB allows users to select a suitable capacity allocation method depending on the use case. The users may opt for the provisioned capacity model if the application has a predictable amount of traffic and requests. In this model, DynamoDB allocates a specified amount of read and write units, and it will keep the resources available even if there is no significant utilization. The on-demand capacity allocation model automatically adjusts the read and write capacity based on the number of requests sent to the database service. This model suits well for applications that have unpredictable spikes of requests. Even though the flexibility of the on-demand model allows for seamless scaling, one of the significant drawbacks of using this model is its unpredictable and expensive costs. Monitoring and managing costs can become complex, especially for applications with highly variable workloads. AWS provides cost management tools, but they require careful configuration and monitoring to avoid unexpected expenses. ### 3. Unable to Use Table Joins DynamoDB has limited options for querying the data within its tables and restricts the complexity of the queries. The database service makes it impossible to query information from multiple tables as it does not support table joins. It becomes a significant drawback since the developers cannot perform complex queries on the data, which are possible in some other competitive products. This limitation often requires developers to denormalize their data, which can lead to data redundancy and increased storage costs. To mitigate this, developers need to carefully design their data models to minimize the need for joins. ### 4. Limited Storage Capacities For Items DynamoDB sets restrictions on most components, which is no different from the limits set for each item size within a DynamoDB table. The size limit for an item is 400KB, and it is essential to note that the users cannot increase this value in any way. This limitation can be restrictive for applications that need to store large objects or documents within a single item. Developers may need to use additional storage solutions, such as Amazon S3, for storing large objects and reference them within DynamoDB items. ### 5. On-Premise Deployments DynamoDB is one of the most successful cloud-native, fully managed database services available in today's market. The service is available for all AWS users keen to deploy their databases on the AWS cloud. Even though the solution has many benefits, one of the major drawbacks is that the solution lacks an on-premise deployment model and is only available on the AWS cloud. This limitation does not allow users to use DynamoDB for applications that require an on-premise database. Although DynamoDB does not offer an on-premise deployment for production environments, it offers an on-premise deployment for development or testing. But, this deployment does not have the same high speeds we expect from DynamoDB and is strictly only for testing. For organizations with strict data residency requirements, this can be a significant limitation. ### 6. Learning Curve and Vendor Lock-In Using DynamoDB effectively requires a good understanding of its unique data modeling principles, which can be different from traditional relational databases. This learning curve can be steep for developers who are new to NoSQL databases. Additionally, since DynamoDB is a proprietary service offered by AWS, there is a risk of vendor lock-in. Migrating to another database service in the future could be complex and costly. Organizations need to weigh the benefits of DynamoDB against the potential challenges of vendor lock-in and consider long-term strategies for data portability.
# Why DynamoDB Fails Most Real-World Apps ... **Brilliant KV at scale. Painful for most business queries.** I shipped a SaaS on DynamoDB. From start to scale during many years. Using DynamoDB as the primary store was one of my worst engineering calls. It feels great in week one: low cost, serverless, fast, safe, replicated, console out of the box. Then reality hits. Most business apps need flexible queries and evolving schemas. DynamoDB punishes both. … ## Two core flaws that sink product teams ### 1) Weak querying for real business needs Business apps rarely stop at “get by id.” They grow into multi-filter lists, admin dashboards, reports, exports, and “can we sort by X then Y?” asks. With DynamoDB: - You sort only within a partition. - Filters happen **after** item selection. - Cross-attribute predicates need GSIs, denormalized views, or both. - Every new dimension risks a backfill, a new GSI, or bespoke glue. … Add or remove a filter? Change the sort priority? Still trivial in SQL. **DynamoDB reality** You’ll end up with a GSI on `(status, created_at)` (maybe per tenant), another index or a composite key to slice by `country`, and you still can’t do a global sort by `created_at, total, order_id` across partitions. You fake it by: - Querying multiple indexes - Merging results in memory - Resorting client-side - Re-paginating manually - Handling holes/dupes across pages ``` // Sketch: 3 filters (status, country, time window) + multi-sort emulation ... ':status': { S: status }, ':since': { N: String(since) }, ':now': { N: String(Date.now()) }, ':country':{ S: 'FR' } ... ScanIndexForward: false, // created_at DESC Limit: 200 // overfetch to emulate secondary sort }).promise()); const merged = (await Promise.all(queries)).flatMap(r => r.Items); // Emulate ORDER BY created_at DESC, total DESC, order_id ASC merged.sort((a, b) => (Number(b.created_at.N) - Number(a.created_at.N)) || (Number(b.total.N) - Number(a.total.N)) || (a.order_id.S.localeCompare(b.order_id.S)) ); const page = merged.slice(0, 50); // manual pagination ``` … ### 2) Query vs Scan forces premature modeling and long-term rigidity This is stated quite hard, you should use Scan in production very carefully and prefer Query in hot paths - for cost and speed matters. DynamoDB makes you pick partition/sort keys and access patterns **upfront**. But real products don’t freeze their questions on day one. You end up: - Over-engineering single-table designs before you have traction - Backfilling GSIs when requirements change - Fighting hot partitions and throughput tuning - Paying in complexity every time you add a filter In an RDBMS, you add an index and move on. In DynamoDB, you plan a migration, tweak streams, write backfills, and hope you didn’t miss a denormalized projection. ## About AWS “workarounds” and their costs You’ll hear: “Keep DynamoDB for writes, then sync to something query-friendly.” - **OpenSearch sync:** $200-$1000 monthly cluster cost, index pipelines, mapping drift, cluster sizing, reindex pain, a new skillset to learn. Also another thing to break. - **RDS/Postgres sync:** At that point, why not just use Postgres first? Dual-write or stream-ingest adds failure modes and ops overhead. - **Athena/Glue/S3 sync:** Fine for batch analytics, not product queries. Latency, freshness, partitioning strategy, and scan-based pricing complicate everything. … - **Streams:** Mixed firehose. Every consumer re-implements routing + type logic. - **Monitoring:** Metrics blur across entity types. Hot keys and throttles are harder to triage. - **PITR/Backups/Restore:** You can’t easily restore “just Orders for tenant X.” It’s all intertwined.

Using DynamoDB in 2025 is such a weird proposition. Horrible dev ...We used it extensively on the second project I mentioned and a couple of other projects for caching / rate limiting and distributed locking needs. Never enabled the persistence layer (which I believe is pretty durable). So we only treated as an ephemeral data store, lowering the architectural complexity of things significantly. Otherwise you need to think about backups, testing backups, clustering in case of scaling needs, I have no idea how persistence works with clustering... DynamoDB is fully managed and solid. mejutoco 9 months ago ... My items are not relations, and I don't see the point in transforming them to and from relational form. And if I did, each row would have like 5 columns set to NULL, in addition to a catch-all string 'data' column where I put the actual stuff I really need. Which is how you slow down an SQL database. So RDBMS is no good for me, and I'm no good for RDBMS. RDBMS offers strong single-node consistency guarantees (which people leave off by default by using an isolation level of 'almost'!). But even without microservices, there are too many nodes: the DB, the backend, external partner integrations, the frontend, the customer's brain. You can't do if-this-then-that from the frontend, since 'this' will no longer be true when 'that' happens. So even if I happen to have a fully-ACID DB, I still lean into events & eventual consistency to manage state across the various nodes. … The thing that would put me off using DynamoDB is the same reason I wouldn't use any other tech - can I download it? For this reason I'd probably reach for Cassandra first. That said I haven't looked at the landscape in a while and there might be much better tools. But it also wouldn't matter what I want to use instead of DynamoDB, because the DevOps team of wherever I work will just choose whatever's native&managed by their chosen cloud provider. … You can manage up to 0 partners easily. Once you go above that threshold, you're into "2-Generals" territory. At that point you're either inconsistent, eventually-consistent, or you're just bypassing your own database and using theirs directly. > dev and user experience are going to be much simpler and easier. … no-SQL initially (for *much better* dev experience) && no-SQL later (for scaling) > When your objects are inconsistently shaped something has to fix them They have one schema (the class file) instead of two (the class file and the SQL migrations). But what happens when that schema defining class file needs to change? You put all your migration code there? How is that different from SQL migrations? … It is my favourite database though (next to S3)! For cases where my queries are pretty much known upfront, and I want predictable great performance. As Marc Brooker wrote in [1], "DynamoDB’s Best Feature: Predictability". I consistently get single digit millisecond GETs, 10-15ms PUTs, and a few more milliseconds for TransactWriteItems. Are you able to complex joins? No. Are you able to do queries based on different hash/sort keys easily? Not without adding GSIs or a new table. The issue in the past few years was the whole craze around "single-table design". Folks took it literally as having to shove all their data in a single table, instead of understanding the reason and the cases that worked well. And with ongoing improvements of DynamoDB those cases were getting fewer and fewer over time.
## Pain Point #1: Deployment Bottlenecks ### The Problem How long does it take your team to get code from commit to production? For most teams, it's days or weeks. Elite teams deploy in under a day. The bottleneck isn't usually the code—it's the deployment process itself. When deployments require specialized knowledge or manual steps, everything slows down. If the one person who knows how to deploy is on vacation, you're stuck. … ### Getting Started You don't need a huge budget to implement this. Start with: - GitHub Actions or GitLab CI for automated pipelines - Docker (used by 59% of professional developers) for consistent environments - Standardized deployment scripts checked into your repo Set up templates for your most common deployment types and build from there. … ## Pain Point #3: Environment Inconsistency ### The Problem "It works on my machine" might be the most frustrating phrase in software development. Environment inconsistencies waste countless hours on debugging issues that only appear in specific environments. When dev, test, and production environments don't match, you're essentially testing different systems. Problems appear out of nowhere during deployment, and fixing them becomes a painful guessing game. … ## Pain Point #4: Cognitive Load from Multiple Tools ### The Problem Most teams juggle 6+ different tools, with 13% managing up to 14 different tools in their development chain. Each tool has its own interface, quirks, and mental model. Learning and remembering how to use all these tools creates massive cognitive overhead, especially for new team members. … ### Getting Started Start by: - Auditing your current toolchain to identify redundancies - Creating consistent interfaces for your most-used tools - Building wrapper scripts that standardize common commands - Setting up a simple internal portal or wiki that provides single-point access ## Pain Point #5: Security & Compliance Overhead ### The Problem Security is crucial but often becomes a productivity killer. Manual security reviews, compliance checks, and remediations consume valuable development time and delay deployments. When security is bolted on at the end rather than built in from the start, it creates friction and frustration. … ## Leveraging What You Already Have The good news? ... Your Git workflow can expand beyond code versioning to include configuration and Infrastructure as Code specs. Those Docker containers you use for local development? With some standardization, they become the basis for consistent environments across your pipeline.
