v0.10.0 (DEPRECATED)

Β· 8 min read

Release date: November 22, 2024

πŸ‘ Highlights​

  • Vector type: GreptimeDB supports vector data types to optimize edge scenarios, such as IoT in vehicles, enabling efficient storage and computation of vector data for real-time perception and AI applications in smart driving.
  • Free index: Inverted indexes are no longer tied to primary keys, allowing users to create them on any column, enhancing query flexibility and efficiency across different scenarios.
  • Alter table options: Enhancements include setting TTL for databases and tables, modifying compaction parameters, and enabling/disabling full-text indexes on columns.
  • Loki remote write: GreptimeDB now supports the Loki remote write protocol, allowing users to log data in Loki format through Grafana tools.
  • Performance Optimization: Up to 10x improvement for queries fetching the latest N records by timestamp (ORDER BY timestamp DESC LIMIT N).

Breaking changes​

  • fix!: replace timeout_millis and connect_timeout_millis with Duration in DatanodeClientOptions by @WenyXu in #4867
  • feat!: Divide flush and compaction job pool by @evenyag in #4871

v0.9.0

Β· 11 min read

Release date: July 16, 2024

πŸ‘ 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.

  • 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.
