Caleb Rackliffe updated CASSANDRA-19567:
----------------------------------------
Reviewers: Caleb Rackliffe
> Minimize the heap consumption when registering metrics
> ------------------------------------------------------
>
> Key: CASSANDRA-19567
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19567
> Project: Cassandra
> Issue Type: Bug
> Components: Observability/Metrics
> Reporter: Maxim Muzafarov
> Assignee: Maxim Muzafarov
> Priority: Normal
> Fix For: 5.x
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> The problem is only reproducible on the x86 machine, the problem is not
> reproducible on the arm64. A quick analysis showed a lot of MetricName
> objects stored in the heap, although the real cause could be related to
> something else, the MetricName object requires extra attention.
> To reproduce run the command run locally:
> {code}
> ant test-jvm-dtest-some
> -Dtest.name=org.apache.cassandra.distributed.test.ReadRepairTest
> {code}
> The error:
> {code:java}
> [junit-timeout] Exception in thread "main" java.lang.OutOfMemoryError: Java
> heap space
