Highlights of Recent PRs

db#6844 Global SST File Recycling (ongoing)

This feature enables SST files to be managed from a global, cluster-wide perspective. It is particularly valuable in scenarios where the Leader Region completes a compaction, allowing delayed deletion of SST files and thereby improving overall storage efficiency.

db#6870 db#6875 db#6881 Migrating More Tests from DuckDB (ongoing)

To enhance the correctness of GreptimeDB’s query engine, we are continuously migrating SQL execution test cases from DuckDB, further strengthening coverage and reliability.

db#6888 db#6923 Bulk Memtable Implementation (ongoing)

The Bulk Memtable feature is actively under development. It is designed to greatly improve GreptimeDB’s write throughput, making it especially well-suited for high-concurrency and large-scale data ingestion scenarios.

db#6889 Improved Time Display in EXPLAIN ANALYZE

Previously, execution times in query plans were displayed as raw numbers (e.g., 1300ns). They are now automatically converted into more human-readable units (e.g., 1.3µs), making it easier for developers to interpret and analyze performance data.

db#6920 Upgrade to Rust 2024 Edition

The GreptimeDB codebase has been upgraded to Rust 2024 Edition. This update not only introduces language-level improvements but also unlocks access to new Rust features that will benefit ongoing and future development.

db#6978 Fixed a deadlock issue when writing metrics via Otel

Resolved a deadlock that could occur when writing metrics through Otel. It is recommended to exercise caution when using Dashmap and perform thorough testing to prevent similar issues.
