---------------------------------------
Summary: Provide additional option to calculate actual object size
Key: HBASE-12001
URL: https://issues.apache.org/jira/browse/HBASE-12001
Project: HBase
Issue Type: Improvement
Components: util
Affects Versions: 2.0.0
Reporter: Mikhail Antonov
(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 attached something like
https://code.google.com/p/memory-measurer/ and provide sort of default
implementaiton of HeapSize which can measure the size of arbitrary object in
bytes. Would require a javaagent to be hooked up.
Thoughts?
