-------------------------------------------
Summary: Coordinator read latency metrics are inflated for some
queries
Key: CASSANDRA-19755
URL: https://issues.apache.org/jira/browse/CASSANDRA-19755
Project: Cassandra
Issue Type: Bug
Components: Observability/Metrics
Reporter: Sam Tunnicliffe
When a partition read is decomposed on the coordinator into multiple single
partition read queries, the latency metric captured in StorageProxy can be
artificially increased.
This primarily affects reads where paging and aggregates are used or where an
IN clause selects multiple partition keys.
