--------------------------------------
Summary: OTLP MetricReporter is inefficient
Key: IGNITE-27355
URL: https://issues.apache.org/jira/browse/IGNITE-27355
Project: Ignite
Issue Type: Improvement
Components: metrics framework ai3
Reporter: Ivan Bessonov
* When you add metrics for partitions within the table (for example) you copy
the entire array {{{{N}}}} times ({{{}{{N}}{}}} - number of local partitions).
This is {{{{O(N*M)}}}} ({{{}{{M}}{}}} - current number of metrics, which is at
least {{{{O(N)}}}} itself).
* When you delete the table, you do the same thing (and it uses
{{{}java.util.Collection#removeIf{}}})
We should use a concurrent hash map instead.
