Ivan Andika updated RATIS-2375:
-------------------------------
Description:
Currently Transaction#cancelTransaction is not used although there is a TODO
comment in RaftServerImpl regarding it.
{code:java}
// TODO: this client request will not be added to pending requests until
// later which means that any failure in between will leave partial state in
// the state machine. We should call cancelTransaction() for failed requests
{code}
We might need to revisit this, maybe we need to use it to implement a rollback
mechanism (similar to RDBMS transaction rollback).
