Release v0.10.1

v0.10.1 (Deprecated)

Release date: November 25, 2024

Deprecated due to a critical issue; please refrain from using it.

👍 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).
• Remove the option: region_engine.mito.max_background_jobs and add three new options: region_engine.mito.max_background_flushes, region_engine.mito.max_background_compactions, and region_engine.mito.max_background_purges for more detailed configuration.
