-------------------------------------
Summary: Reducing memory overhead associated with strings in
MetricName
Key: KAFKA-10012
URL: https://issues.apache.org/jira/browse/KAFKA-10012
Project: Kafka
Issue Type: Improvement
Components: network
Reporter: Navina Ramesh
{{SelectorMetrics}} has a per-connection metrics, which means the number of
{{MetricName}} objects and the strings associated with it (such as group name
and description) grows with the number of connections in the client. This
overhead of duplicate string objects is amplified when there are multiple
instances of kafka clients within the same JVM.
This patch address some of the memory overhead by making {{metricGrpName}} a
constant and introducing a new constant {{perConnectionMetricGrpName}}.
Additionally, the strings for metric name and description in {{createMeter}}
have been interned since there are about 8 per-client and 4 per-connection
{{Meter}} instances.
