Pending tasks should probably not include active tasks
------------------------------------------------------
Key: CASSANDRA-3455
URL: https://issues.apache.org/jira/browse/CASSANDRA-3455
Project: Cassandra
Issue Type: Improvement
Components: Core
Affects Versions: 1.0.0, 0.8.0
Reporter: Sylvain Lebresne
Assignee: Sylvain Lebresne
Priority: Minor
Fix For: 0.8.8, 1.0.3
Attachments: 0001-Update-pending-task-count.patch
In our TheadExecutor JMX metrics, 'pending tasks' includes 'active tasks'
(because it's taskCount-completedTaskCount). I think this is counter-intuitive
for most people (of course you could define 'pending tasks' as the 'pending of
being fully executed' but you usually want pending to indicate if there is
tasks that have to wait to be executed). Besides, I believe the initial
intention was not to have pending to include active given the following comment:
{noformat}
/**
* Get the number of tasks waiting to be executed
*/
public long getPendingTasks()
{noformat}
This ticket propose to fix that.
