-------------------------------------------
Summary: 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
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}
