Denis Mekhanikov commented on IGNITE-9009:
------------------------------------------
[~agoncharuk], backups won't be notified, because they don't store the event
queue. There are no ACKs sent to the backups.
I think, local continuous queries should work in isolation from each other.
If processing of cache events locally on all primary nodes is required, then
[Cache#registerCacheEntryListener|https://static.javadoc.io/javax.cache/cache-api/1.0.0/javax/cache/Cache.html#registerCacheEntryListener(javax.cache.configuration.CacheEntryListenerConfiguration)]
should be used.
> Local continuous query listeners may be called on partition reassignment

> When a node becomes primary for some partitions, then local continuous query
> listeners receive updates on entries from that partitions. Such invocations
> shouldn't happen.
> Attached test class demonstrates this behaviour.
