James Taylor commented on PHOENIX-1263:
---------------------------------------
Since the entire stats collection scheme is predicated on scanning the entire
region, it's unlikely we'll change ANALYZE to use the guideposts.
Did you post a new patch yet, [~ramkrishna]? Probably a good idea to catch the
3.0 branch up with 4.0 first and then tackle PHOENIX-1263 separately (as this
one needs to be in all branches).
> Only cache guideposts on physical PTable

> Rather than caching the guideposts on all tenant-specific tables, we should
> cache them only on the physical table. On the client side, we should also
> update the cache with the latest for the base multi-tenant table when we
> update the cache for a tenant-specific table. Then when we lookup the
> guideposts, we should ensure that we're getting them from the physical table.
> Otherwise, it'll be difficult to keep the guideposts cached on the PTable in
> sync across all tenant-specific tables (not to mention using quite a bit of
> memory).
