InfluxDB has released a critical maintenance update for its OSS (Open Source Software) and Enterprise versions, addressing a defect that could cause data loss in shards larger than 16GB. The update fixes several issues, including removing a caching mechanism that could lead to data corruption and improving the performance of time-series databases. Users are encouraged to upgrade as soon as possible, but can temporarily prevent full compaction from running by modifying their configuration. Downgrading is also an option, although it may require rebuilding the index if using Time Series Intelligence (TSI). The update includes fixes for issues with caching bitmaps in TSI and converting TagValueSeriesIDCache to use string fields.
