--------------------------------
Summary: Make saga-actuator execute SQL one by one while
integrating with ShardingSphere
Key: SCB-1276
URL: https://issues.apache.org/jira/browse/SCB-1276
Project: Apache ServiceComb
Issue Type: Improvement
Components: Saga
Reporter: cherrylzhao
Fix For: saga-0.4.0
currently, we have integrated with saga using graph based engine in
shardingsphere
it need us to collect all participated actual SQL, then submit to saga actuator
in commit/rollback phase.
if application crashed before invoking saga actuator, undo log of branch
transaction SQL will not be saved,
so recovery thread will not be executed correctly.
it's better that encapsulating every actual SQL as a saga task in
shardingsphere side,
then submit to saga actuator realtime instead of batch processing all the SQLs
at commit/rollback phase.
this architecture will make the boundary more clear between shardingsphre and
saga, currently we have done some additional works for integrating saga.
