• Add environment variable support, deployment support, document add deployment support
• dtmcli is completely decoupled from gin and logrus, and supports splitting into separate warehouses
• Add transaction wait result mode
• Add the default DB_DRIVER to mysql

DTM is the first golang open source distributed transaction manager, which elegantly solves distributed transaction problems such as idempotence, null compensation, and suspension. Provides a simple, easy-to-use, high-performance, and easily horizontally scalable distributed transaction solution.

Invited to participate in the China Database Conference to share distributed transaction practice in a multilingual environment

  • Support HTTP, provide a very simple interface, greatly reduce the difficulty of getting started with distributed transactions, and novices can quickly access

• Simple to use

  • Developers no longer worry about suspension, null compensation, idempotence, etc., and the framework will handle it on their behalf

• Cross language

  • It is suitable for companies with multi-language stacks. Convenient to use in various languages such as go, python, php, nodejs, ruby, and c#.

• Easy to deploy, easy to expand

  • Only rely on mysql, easy to deploy, easy to cluster, easy to expand horizontally

Compared with other frameworks

At present, the open source distributed transaction framework has not yet seen a mature framework for non-Java languages. There are many Java languages, such as Ali's SEATA, Huawei's ServiceComb-Pack, JD's shardingsphere, and himly, tcc-transaction, ByteTCC, etc., among which seata is the most widely used.

The following is a comparison of the main features of dtm and seata:

characteristic	DTM	SEATA	Remark
Support language	Go、Java、python、php、c#...	Java	dtm can easily access a new language
Exception handling	Sub-transaction barrier automatic processing	Manual processing	dtm solves idempotence, suspension, and null compensation
TCC affairs	✓	✓
XA affairs	✓	✓
AT affairs	✗	✓	AT is similar to XA, with better performance, but with dirty rollback
SAGA affairs	Simple mode	State machine complex pattern	The state machine mode of dtm is under planning
Transaction message	✓	✗	dtm provides transaction messages similar to rocketmq
letter of agreement	HTTP、GRPC	Protocols such as dubbo, no HTTP	dtm is more cloud-native

From the features of the comparison above, if your language stack includes languages other than Java, then dtm is your first choice. If your language stack is Java, you can also choose to access dtm and use sub-transaction barrier technology to simplify your business writing.
