Ahmed Bashir created CASSANDRA-4790:
---------------------------------------
Summary: Allow property override of available processors value
Key: CASSANDRA-4790
URL: https://issues.apache.org/jira/browse/CASSANDRA-4790
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 1.1.4
Reporter: Ahmed Bashir
Currently, many critical thread pools are sized according to the number of
available processors i.e. Runtime.getRuntime.availableProcessors() (See
StageManager.java)
In a multi-instance deployment, multiple Cassandra instances will independently
assume that all processors are available to it; there should be a mechanism to
specify a smaller set of processors (and perhaps have affinity).
