-----------------------------------
Summary: Only call Histogram#getStatistics() once per set of
retrieved statistics
Key: FLINK-12984
URL: https://issues.apache.org/jira/browse/FLINK-12984
Project: Flink
Issue Type: Sub-task
Components: Runtime / Metrics
Reporter: Nico Kruber
Assignee: Nico Kruber
In some occasions, {{Histogram#getStatistics()}} was called multiple times to
retrieve different statistics. However, at least the Dropwizard implementation
has some constant overhead per call and we should maybe rather interpret this
method as returning a point-in-time snapshot of the histogram in order to get
consistent values when querying them.
