v0.9.0

Release date: July 16, 2024

👍 Highlights

  • Log Engine: Supports logging ingestion, pipeline and full-text index. GreptimeDB is now a unified time-series database for both metrics, events, and logs (trace in plan).
  • Region Failover A lot of testing work has been done 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.
  • InfluxDB Merge Read: You can now use the merge_mode=last_non_null table option to allow SELECT result merges all the last non-null fields.
  • gRPC TLS: You can now set up the grpc.tls config to turn on TLS for gRPC connection.
  • Manually Compact in Strict Window: You can now use SELECT COMPACT_TABLE("monitor", "strict_window", "3600"); to manually schedule a compaction task, splitting SST files strictly into time windows. The third option is the time window's width in seconds.
