seata-golang is a distributed transaction middleware based on Golang.

A typical lifecycle of Seata managed distributed transaction:

• TM asks TC to begin a new global transaction. TC generates an XID representing the global transaction.
• XID is propagated through microservices' invoke chain.
• RM registers local transaction as a branch of the corresponding global transaction of XID to TC.
• TM asks TC for committing or rolling back the corresponding global transaction of XID.
• TC drives all branch transactions under the corresponding global transaction of XID to finish branch committing or rolling back.

• cmd: to startup TC server
  • profiles/dev/config.yml: TC config file
  • tc/main.go: TC startup entrance
• dist: to build in docker container
• docs: documentations
• pkg: TC + RM + TM implementation
  • server/db/*.sql: sql scripts to create DB and tables for TC

• TC server

cd ${projectpath}/cmd/tc
go build -o tc_server
# create database `seata` for TC server
# update storage.dsn.mysql in ${projectpath}/cmd/profiles/dev/config.yml
./tc_server start -config ${projectpath}/cmd/profiles/dev/config.yml
