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
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.ymlPlease refer to demo seata-go-samples
-
- MySQL server
- Golang version >= 1.15
- Business tables that require primary key
The seata-golang AT and TCC design are actually the same as seata.
