Revision - 86a0133 - PlainTableReader to expose index size to users

Revision 86a0133d0527a1005ebd9b517fa973c1a4a0a1ae authored by sdong on 23 April 2014, 01:31:55 UTC, committed by sdong on 23 April 2014, 02:29:05 UTC

PlainTableReader to expose index size to users

Summary:
This is a temp solution to expose index sizes to users from PlainTableReader before we persistent them to files.
In this patch, the memory consumption of indexes used by PlainTableReader will be reported as two user defined properties, so that users can monitor them.

Test Plan:
Add a unit test.
