Brandon Williams created CASSANDRA-5135:
-------------------------------------------
Summary: calculatePendingRanges could be asynchronous
Key: CASSANDRA-5135
URL: https://issues.apache.org/jira/browse/CASSANDRA-5135
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 1.1.0
Reporter: Brandon Williams
Assignee: Brandon Williams
Fix For: 1.1.9
In the vein of CASSANDRA-3881, cPR is expensive and can end up dominating the
gossip thread, causing all sorts of havoc. One simple way we triage this is to
simply give it it's own executor with a queue size of 1 (since we don't
actually need to recalculate for every host we see if we suddenly see many of
them) and do the calculation asynchronously, freeing up the gossiper.
