dtmcli-java is the Java client SDK for distributed transaction managerdtm
DTM is a distributed transaction framework which provides cross-service eventual data consistency. It provides saga, tcc, xa, 2-phase message, outbox patterns for a variety of application scenarios. It also supports multiple languages and multiple store engine to form up a transaction as following:
- Support for multiple languages: Go, Java, PHP, C#, Python, Nodejs SDKs
- Support for multiple transaction patterns: SAGA, TCC, XA
- Support for OutBox pattern: 2-phase messages, a more elegant solution than OutBox
- Support for multiple database transactions: Mysql, Redis, MongoDB, Postgres, TDSQL, etc.
- Support for multiple storage engines: Mysql (common), Redis (high performance), MongoDB (in planning)
- Support for multiple microservices architectures:go-zero, go-kratos/kratos, polarismesh/polaris
- Support for high availability and easy horizontal scaling
