v0.9.0

· 11 min read

Release date: July 16, 2024

👍 Highlights​

  • Log Engine: GreptimeDB is now a unified time-series database for both metrics, logs, and events (trace in plan).
  • Remote WAL is significantly improved and is now recommended to turn on.
  • Table View: You can now CREATE VIEW on tables and treat them as logical table.
  • Short interval literal for user experience.
