Hoss Man created SOLR-6968:
------------------------------
Summary: add hyperloglog in statscomponent as an approximate count
Key: SOLR-6968
URL: https://issues.apache.org/jira/browse/SOLR-6968
Project: Solr
Issue Type: Sub-task
Reporter: Hoss Man
stats component currently supports "calcDistinct" but it's terribly inefficient
-- especially in distib mode.
we should add support for using hyperloglog to compute an approximate count of
distinct values (using localparams via SOLR-6349 to control the precision of
the approximation)
