SQLite file-level locking causes write concurrency bottlenecks

8/10 High

SQLite uses file-level locking that locks the entire database during write operations, preventing concurrent writes. This becomes a critical bottleneck in applications with background workers, asynchronous operations, or high-frequency write patterns, and can easily lead to deadlocks.

Query: “What are the most common pain points with SQLite for developers in 2025?”4/5/2026

SQLite is not ideal for applications with a high level of concurrent write operations. It locks the entire database during a write operation, which can cause a bottleneck... it is easy to get ourselves into situations of Deadlocks when background jobs are trying to write to the database at the same time.
