HeLifu updated KUDU-2887:
-------------------------
Description: The patch about aggregating tablet statistics on the
kudu-master is on the way. And I think it's important to expose these
statistics in client api by which the query engine can optimize their query
plan. For example: (1) adjust the order of scanning tables, (2) Split a big
tablet into multiple range pieces(KUDU-2437) to improve concurrency
automatically, (3) speed up the query like "select count( *) from table".
