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

MongoDB can lose data in many startling ways... They just disappeared sometimes. Cause unknown. Recovery on corrupt database was not successful. Replication between master and slave had *gaps* in the oplogs, causing slaves to be missing records the master had.
