influxdata/influxdb v1.13.1

on GitHub

Features

• mTLS support: Add mutual TLS (mTLS) authentication for the HTTP, OpenTSDB, and subscriber services, including certificate reload on SIGHUP and separate client and server certificate configuration. (#27534, #27543)
• Adaptive TSI cache sizing: The series-id-set-cache-size cache can now grow and shrink itself between a configurable floor and ceiling based on the measured query hit rate, instead of staying at one fixed size. Configure it with the new series-id-set-cache-max-size, series-id-set-cache-target-hit-rate, and series-id-set-cache-shrink-conservatism settings. Monitor it through the new tsi1_cache SHOW STATS measurement. (#27480, #27552)
• hardening-enabled: Add a hardening-enabled configuration option that restricts Flux HTTP requests to public addresses, mitigating server-side request forgery (SSRF). Disabled by default to preserve existing behavior. (#27488)
• Backup compression: Add a -gzipCompressionLevel flag to influxd backup for trading compression ratio against speed. (#27293)
• Broader config value formats: Size and duration configuration settings now accept a wider range of human-readable input formats, while remaining compatible with all previously accepted values. (#27376)
• SHOW MEASUREMENTS: Support partial results when some shards are unavailable. (#27443)
• Operational visibility: Failed and slow queries, per-user query and write byte statistics (opt-in), the remote host and user in query logs, compaction planning statistics, continuous query diagnostics, and TSM file-store merge metrics are now available through SHOW STATS, /debug/vars, and EXPLAIN ANALYZE. (#27536, #27547, #27188, #27528, #26981, #27523, #26874, #26615, #26624)

Bug Fixes

• Fixed a potential deadlock and reduced lock contention between compactions and hot query reads in the TSM file store by splitting its single lock into separate fast and slow paths. (#27501)
• Corrected several TSI compaction-planning and lock-contention issues. (#27146, #27123, #26649, #26647, #26432)
• Fixed authorizer leakage in SHOW queries. (#27196)

Notes

• This is identical code to InfluxDB OSS v1.13.0. Only the version number has changed.
