Hi All,
I have Ignite cluster which consists of two nodes. Each node after start
creates a continuous query which calls atomicLong.incrementAndGet() in
"onUpdated" method:
continuousQuery.setLocalListener(new
CacheEntryUpdatedListener<Integer, String>() {
@Override public void onUpdated(Iterable<CacheEntryEvent<?
extends Integer, ? extends String>> evts) {
for (CacheEntryEvent<? extends Integer, ? extends String> e
: evts){
System.out.println("Incremented value: " +
atomicLong.incrementAndGet());
}
}
});
This continuous query is listening on all events on "test" cache.
I start both nodes and then start a client application which inserts 5
entries into "test" cache. For the first two entries (which client inserts)
I see below outputs only on one node:
Incremented value: 1
Incremented value: 2
And after that I get below warn messages in logs on the node where
"Incremented value" was printed (on the second node I see no messages) :

After that I see:

org.apache.ignite.internal.diagnostic : Found long running transaction
and
2018-07-09 21:57:58.021 WARN 1876 --- [eout-worker-#23]
org.apache.ignite.internal.diagnostic : Found long running cache future
Please help me understand if my way of using atomicLong is incorrect or
there is something else?
Thank you in advance for assistence.
