Subject [saga-actuator]consider about adding StreamBasedSaga engine to integrate with shardingsphere
Date Fri, 26 Apr 2019 10:39:38 GMT
Hi, all

currently, we have integrated with saga using graph based engine in shardingsphere[1]
it need us to collect all participated actual SQL, then submit to saga actuator in commit/rollback
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
this architecture will make the boundary more clear between shardingsphre and saga, currently
we have done some additional works for integrating saga.

any thought?
