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?
