+ # Originally, Akka and Pekko Persistence implementations rearranged
responses to match the
+ # request order. But this feature wasn't guaranteed by the test suite,
and nothing in the
+ # internals relied on it.
#
# As this ordering is global, slow write requests for some entities can
stall writes for all,
# which can cause latency issues under load.
#
- # The old behaviour is still enabled by default ("on"). After more
testing on existing applications,
- # the default might be switched to "off", and eventually this option
might be removed altogeter, leaving
- # "off" the only behaviour available.
+ # When this setting is "off", the journal plugin is allowed to send back
write responses
+ # in any order. This can improve throughput and reduce latency under
load.
+ # When using "off", changes to the dispatcher configuration of the
journal plugin
+ # can lead to an increased number of out-of-order responses.
