---------------------------------------
Summary: StateTracker#bucketAccessed should be called each time
access to the bucket
Key: APEXMALHAR-2332
URL: https://issues.apache.org/jira/browse/APEXMALHAR-2332
Project: Apache Apex Malhar
Issue Type: Bug
Reporter: bright chen
Assignee: bright chen
StateTracker#bucketAccessTimes keep the bucket access time order by access
time. It was used by free memory thread to decide which bucket can be freed.
So, each access to bucket include put and get should update the access time.
As bucketAccessTimes and bucketHeap are shared by two thread. update them for
each operation could impact the performance. It better to update period. As
Bucket don't support window operation. I am going to keep the update time and
update when time out.
