James Taylor commented on PHOENIX-4722:
---------------------------------------
FYI, [~cody.mar...@gmail.com] - more ideas to improve the client-side caching
of stats.
> Pull over only guideposts necessary for client side stats cache
> ----------------------------------------------------------------

> Key: PHOENIX-4722
> URL: https://issues.apache.org/jira/browse/PHOENIX-4722
> Project: Phoenix
> Issue Type: Improvement
> Reporter: James Taylor
> Priority: Major
>
> Our current client-side cache for statistics pull over all guideposts for a
> table. Since we know the start/stop key of the scans for a query, we could
> have a more granular approach and only pull over the guideposts we need. The
> cache maintenance and retrieval would get somewhat more complicated, though,
> as we'd need to combine ranges together in the cache as we pull them over and
> still get a cache hit across what was potentially multiple different ranges.
