Yury Gerzhedovich commented on IGNITE-10688:
--------------------------------------------
[~vozerov],
# Yes, 'statio' prefix used by postgres. But I've changed name of the view to
suggested by you CACHE_GROUPS_IO.
# Rename CACHE_GRP_NAME column to GROUP_NAME and add new GROUP_ID.
# Yes, it is so. Added corresponded test.
# Ok, removed view for indexes.
If I right understood your note, you mean GROUP_ID name for column instead of
GROUP_NAME.
