Compare OceanBase

OceanBase compared with MySQL, PostgreSQL, Oracle, and TiDB: scale-out, HA, HTAP, and migration trade-offs.

• Comparison

  OceanBase vs MySQL

  OceanBase versus MySQL for write scale-out, multi-zone Paxos HA, HTAP reporting, and OMS-based migration from a single primary.

• Comparison

  OceanBase vs PostgreSQL

  OceanBase versus PostgreSQL: no native PostgreSQL mode, extension and procedural-code gaps, and when distributed MySQL-mode OceanBase is the wrong target.

• Comparison

  OceanBase vs Oracle

  OceanBase Oracle mode versus Oracle Database: SQL and PL/SQL coverage, RAC-style assumptions, licensing pressure, and what a mode switch cannot fix.

• Comparison

  OceanBase vs TiDB

  OceanBase versus TiDB for distributed MySQL-facing workloads: log-stream Paxos versus TiKV, operational tooling, and HTAP design differences.
