Ivan Andika commented on HDDS-12008:
------------------------------------
[~szetszwo] I have a few related questions:
* In Ratis Async Pipeline, PutBlock is only done when the log entry is to be
applied in StateMachine#applyTransactions. However, seems in Streaming Write
Pipeline, the PutBlock is called in ContainerStateMachine#link, which is under
WriteLog. Meaning that PutBlock might never be committed if the log is
truncated. May I know whether it is correct to call trigger PutBlock
ContainerStateMachine#link?
** Maybe it's better to handle it in StateMachine#applyTransaction triggered
by sendForward. However, I'm not entirely sure whether
StateMachine#applyTransaction will be triggered as part of sendForward.
* Any possible ideas regarding the truncation logic of a "linked" LogEntry? Do
we need to delete the files, etc?
