Yury Gerzhedovich commented on IGNITE-11451:
--------------------------------------------
[~nizhikov], there at least two reasons to have separate view for index IO
statistics:
1) It common approach for other vendors (see
https://cwiki.apache.org/confluence/display/IGNITE/IEP-27%3A+Page+IO+statistics)
2) View INDEXES contains only static information. New one contain dynamic
changed information.
WDYT? Is it reasonable?
