> Key: IGNITE-13949
> URL: https://issues.apache.org/jira/browse/IGNITE-13949
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.9.1
> Reporter: Yaroslav Molochkov
> Assignee: Yaroslav Molochkov
> Priority: Major
> Fix For: 2.11
>
> Time Spent: 10m
> Remaining Estimate: 0h

> Right now
> org.apache.ignite.internal.processors.cache.PartitionUpdateCounterTrackingImpl
> has 2 AtomicLong variables, cntr and reserveCntr, but there are some
> methods, that are unsynchronised, e.g. next:
> {code:java}
> @Override public long next() {
> long next = cntr.incrementAndGet();
> reserveCntr.set(next);
> return next;
> } {code}
> Even though both are AtomicLong, operation like "get then set" is a composite
> one and should be atomic in the context of an object that holds these
> variables.
