OceanBase

DEVOPS
Velocity5.0

Distributed relational database with native support for HTAP workloads

oceanbase.github.io ↗

OceanBase's older branches now get backup and replication upgrades, not just vector-index fixes.

distributed databasevector searchhybrid searchbackup and recoveryhtap
◆Current state
OceanBase Community Edition runs several branches in parallel, with 4.6.0 and its 5.0.1 continuation carrying the hybrid vector, full-text and scalar search work. 4.6.0 BP1 in late October extended the Elasticsearch-compatible hybrid search. On the 4.4.2 line, BP3 in September added secondary archive backup destinations, async PL execution in MySQL mode and disk-balancing changes, and 4.2.5 BP8 allowed backup credentials to be rotated in place.
◆Where it's heading
The newest lines are where retrieval features land; the LTS bundle patches now focus on backup, disaster recovery and performance, following the RPO=0 standby sync that became supported in 4.4.2 BP2.
◆Prediction
Expect a 5.0.x release extending the 4.6 retrieval work, and further bundle patches on 4.4.2 and 4.2.5 focused on operations.

    OceanBase 4.6.0 BP1 widens ES-compatible hybrid search

    The 4.6.0 bundle patch extends OceanBase's Elasticsearch-compatible hybrid search with num_candidates, wildcard filters, terms aggregations, collapse and custom sort, and adds parallel scans inside a single query path. Parallel execution is off by default and costs more CPU when on.

    OceanBase 4.2.5 CE BP8: in-place backup credential rotation

    OceanBase 4.2.5 CE BP8 lets backup and archive destination keys be rotated in place with ALTER SYSTEM, alongside bug fixes. Upgrade paths from older 4.2.x builds may need intermediate versions.

    OceanBase 4.4.2 BP3 adds tiered log archive backup and async PL

    A bundle patch with real operations work: log archives can be copied to a secondary backup destination, backups skip nearly full servers and retry on disk-full, and MySQL-mode PL can run asynchronously. It extends the 4.4.2 line's focus on availability that began with RPO=0 standby sync.

    OceanBase 5.0.1 adds parallel DDL and online storage-format conversion

    Framed in its own release notes as a continuation of V4.6.0 rather than a new direction, despite the major version number. The substance is engine maturity: parallel DDL for adding and dropping columns and for partition operations, deferred online conversion from columnar and hybrid layouts back to row storage which completes the conversion matrix between all three formats, random-distribution tables, and Zone-level and subpartition table groups.

    OceanBase 4.4.2 BP2 makes RPO=0 standby sync officially supported

    Strong synchronous replication to a standby graduates from experimental in BP1 to formally supported here, with maximum-protection and maximum-availability modes that differ in whether the primary halts writes or degrades to async when the standby link fails. Promotion of an existing feature rather than new capability, but it is the piece that lets the LTS line be used where zero data loss is a hard requirement.

    v4.6.0_CE

    ⚡ SPARK

    This is the release the rest of the window orbits: V5.0.1 describes itself as its continuation, and the vector-index defects filling the 4.4.1 and 4.3.5 hotfix branches are the cost of the search work landing here. It marks the point where AI retrieval stops being a bolted-on index type and becomes part of the query engine.
