I'm running pojocache 2.0.0 CR3 in a standalone two node active/hot-standby cluster
and I'm running into problems when brining up the second node (the hot-standby).
I'm using the replySync-service.xml configuration from the example code (using TCP
instead of multicast UDP). The active node is updating the cache frequently (about once
per second). When the hot-standby node comes online, the active node will almost always
throw a TimeoutException during the state transfer because it will continue updating the
cache during the state transfer. The interleaving of the cache update and the state
transfer appears to cause a deadlock, which results in the TimeoutException being thrown.
The replicated state is fairly small (a Map<String, String> with less than 100
entries). I registered a custom @CacheListener class that listens for ViewChanged events
and prevents the active node from writing to the pojocache for the next five seconds and
the problem seems to have gone away. Is there a better way to do this? Is there any way to
hook into the underlying replication code to prevent cache operations during replication?
Are there any configuration settings that can be used to prevent cache operations during
replication?
