## What it is
OceanBase is a distributed relational database engine developed by Ant Group, offering MySQL compatibility, Paxos-based high availability, and HTAP (hybrid transactional/analytical) processing. It also supports vector search and full-text search, positioning itself as a unified multi-model database for demanding workloads.

## Use cases
- run a horizontally scalable MySQL-compatible OLTP database
- combine transactional and analytical workloads in one HTAP engine
- store and search vector embeddings for AI applications
- achieve zero data loss with fast failover using Paxos replication
- migrate from MySQL to a distributed database without rewriting queries
- handle PB-scale data across hundreds of nodes

## When to choose
- you need linear scalability and high availability beyond what a single MySQL instance provides
- you want real-time analytics on transactional data without a separate OLAP system
- you need MySQL compatibility for easy migration
- you want vector and full-text search built into your relational database

## When to avoid
- you have a small single-node workload where a standard RDBMS is simpler
- you need PostgreSQL rather than MySQL compatibility
- you cannot operate a distributed database cluster with its operational complexity

## Facets
- artifact type: application
- maturity: stable
- function: database, vector-database, search-engine, caching
- domain: databases, microservices, big-data, analytics
- platform: cloud, self-hosted
- tags: htap, paxos, mysql-compatible, oltp, olap, distributed-sql, vector-search, fulltext-search, high-availability, search, linux, docker, kubernetes
