OceanBase vs Prometheus

OceanBase vs Prometheus: at a glance
What is OceanBase?
OceanBase is rebuilding itself as a RAG backend without giving up the HTAP story
OceanBase Community Edition runs at least five branches in parallel — 4.2.5, 4.3.5, 4.4.1, 4.4.2, 4.6.0 and now 5.0.1 — with feature releases on the newest lines and hotfix trains keeping older LTS branches alive. The centre of gravity in this window is V4.6.0, which added a native SQL hybrid-retrieval interface fusing vector, full-text and scalar predicates in one query and reworked the execution framework behind it. The hotfix branches show where that work is straining: 4.4.1 and 4.3.5 patches are dominated by vector-index bugs — HNSW memory blowups, IVF cache leaks, index rebuilds hanging, planner misjudgements that skip the vector index entirely.
What is Prometheus?
Two branches running in parallel: 3.13 LTS on security patches, 3.14 promoting experiments to stable.
Prometheus is maintaining a 3.13 LTS line and a 3.5 line with security-only releases while 3.14 develops. The LTS patches have been narrow and serious — a head-chunk cache returning samples from the wrong chunk after truncation, a SIGBUS crash when the active query tracker's disk fills, plus CVE-driven dependency bumps in golang.org/x/text and gRPC. The 3.14.0 release candidate is where the feature work sits: duration expressions on by default, first_over_time promoted out of the experimental flag, and Oracle Cloud Infrastructure service discovery added.

◆ Current state
OceanBase Community Edition runs at least five branches in parallel — 4.2.5, 4.3.5, 4.4.1, 4.4.2, 4.6.0 and now 5.0.1 — with feature releases on the newest lines and hotfix trains keeping older LTS branches alive. The centre of gravity in this window is V4.6.0, which added a native SQL hybrid-retrieval interface fusing vector, full-text and scalar predicates in one query and reworked the execution framework behind it. The hotfix branches show where that work is straining: 4.4.1 and 4.3.5 patches are dominated by vector-index bugs — HNSW memory blowups, IVF cache leaks, index rebuilds hanging, planner misjudgements that skip the vector index entirely.
◆ Where it's heading
Two threads run side by side and neither is being sacrificed. One is AI data infrastructure: hybrid search, sparse vectors, recall evaluation, Document AI and an explicitly named end-to-end RAG package, plus AI Functions that now handle images. The other is the HTAP and availability core: columnar replica routing with consistent reads, primary/standby strong sync at RPO=0 graduating from experimental to supported inside two releases, and V5.0.1 completing online conversion between row, columnar and hybrid storage formats. Note that publication dates on this feed do not match the stated release dates in the entries, so cadence read off timestamps alone will be misleading.
◆ Prediction
The volume of vector-index defect fixes across three hotfix branches suggests the next releases on the 5.0 line will spend more effort stabilising hybrid search than extending it, with the RAG packaging work more likely to be documented and productised than expanded.
Prometheus
5.0DEVOPS
Two branches running in parallel: 3.13 LTS on security patches, 3.14 promoting experiments to stable.
◆ Current state
Prometheus is maintaining a 3.13 LTS line and a 3.5 line with security-only releases while 3.14 develops. The LTS patches have been narrow and serious — a head-chunk cache returning samples from the wrong chunk after truncation, a SIGBUS crash when the active query tracker's disk fills, plus CVE-driven dependency bumps in golang.org/x/text and gRPC. The 3.14.0 release candidate is where the feature work sits: duration expressions on by default, first_over_time promoted out of the experimental flag, and Oracle Cloud Infrastructure service discovery added.
◆ Where it's heading
PromQL is the centre of gravity. Features enter behind promql-experimental-functions or a dedicated flag, get renamed once while experimental (min/max to min_of/max_of), then graduate — first_over_time and duration expressions are the current graduates, start_timestamp the next candidate behind use-start-timestamps. The API is simultaneously being tightened, with the stats parameter deprecated ahead of rejection in the next major and credential forwarding across redirects already removed in 3.13. Service discovery keeps absorbing clouds as their APIs change, OCI added and a Hetzner label dropped in the same release.
◆ Prediction
A 3.14.0 final should follow the release candidate within weeks, carrying the duration-expression and first_over_time promotions with it.
