----------------------------------------------
Summary: Calculate pending ranges for identical KS settings just
once
Key: CASSANDRA-12870
URL: https://issues.apache.org/jira/browse/CASSANDRA-12870
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Stefan Podkowinski
Assignee: Stefan Podkowinski
Fix For: 4.0
The {{TokenMetadata.calculatePendingRanges()}} operation can be very expensive
and already has been subject to micro optimization in CASSANDRA-9258. Instead
of further optimizing the calculation itself, I'd like to prevent it from being
executed as often by only calling it just once for all keyspaces sharing
identical replication settings.
