[jira] [Updated] (APEXMALHAR-2321) Improve Buckets memory management

     [ https://issues.apache.org/jira/browse/APEXMALHAR-2321?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

bright chen updated APEXMALHAR-2321:
------------------------------------
    Description: 
Currently buckets were managed as an array. Each bucket have memory limitation, and free memory will be triggered if the bucket memory usage over the limitation.

- For ManagedTimeUnifiedStateImpl, the default bucket number is 345600, which probably too large.


- The default maxMemorySize is zero. It's better to give a default reasonable value to avoid too much garbage collection

- For ManagedTimeUnifiedStateImpl, the default bucket number is 345600, which probably too large.

- AbstractManagedStateImpl.maxMemorySize probably will be misunderstand as the max memory size of total managed state, but in fact it was used as memory size of each bucket. Better to rename it.

- The default maxMemorySize is zero. It's better to give a default reasonable value to avoid too much garbage collection
