[jira] [Updated] (HBASE-12001) Provide additional option to
calculate actual object size
[ https://issues.apache.org/jira/browse/HBASE-12001?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mikhail Antonov updated HBASE-12001:
------------------------------------
Description:
(May be it was discussed elsewhere and I missed it, in that case I'm sorry :) )
Currently there's HeapSize interface, marked as the one useful to measure caches, and some implementation thereof computing the sizes of different objects.
I was thinking to add something like https://code.google.com/p/memory-measurer/ and provide sort of default implementation of HeapSize which can measure the size of arbitrary objects in bytes. Would require a javaagent to be hooked up.
Thoughts?
