Hi HN — I’m the creator of GreptimeDB. We just shipped v1.0.0-rc.1 (our first 1.0 release candidate / feature-freeze milestone).

Highlights:

Online region repartition (SPLIT/MERGE) to adjust partitions at runtime (distributed clusters; shared object storage + GC).

Faster Metric Engine PK filters via memcomparable byte comparisons (microbench: ~20–90× on dense codec).

PromQL planner prefers TSID (skips unnecessary label columns).

Would love feedback from folks running observability/time-series workloads, especially on upgrade paths + repartition behavior in real clusters. GitHub releases/changelog: https://github.com/GreptimeTeam/greptimedb/releases
