-------------------------------------
Summary: 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
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.
