Thawan Kooburat commented on ZOOKEEPER-1798:
--------------------------------------------
The observer don't need to wait for a request to be persisted on disk before
applying to the db right?
Currently, the test is failing because of timing issue but this shouldn't
affect the correctness of the system. So we just add some delay in the test or
some mechanism to make sure that request get flushed before we do the verify
step instead. So we don't have to pay for the cost of extra latency on running
system.
