v1.1.4

· 阅读需 2 分钟

Release date: July 24, 2026

GreptimeDB v1.1.4 is a focused maintenance release improving correctness for streaming Flow expiration and timestamp presentation over MySQL. It also includes stability, query-validation, metadata-client, and storage fixes.

We recommend users on earlier v1.1 releases upgrade to v1.1.4.

👍 Highlights​

  • Streaming Flow EXPIRE AFTER values are now converted to the correct time unit, preventing state from expiring too early. Negative values are rejected while 0 remains valid.
  • MySQL timestamp results now respect the column's configured precision, avoiding padded millisecond values and truncated nanosecond values.
  • MetaSrv leader caching is now enabled correctly after leader election, restoring leader-side metadata-cache performance.
  • Compaction scheduling now removes stale status after throttling, so later compaction work can continue normally.
