Mikhail Khludnev created SOLR-18477:
---------------------------------------
Summary: faster intersection, and omit stored fields for
auxIndexJoin
Key: SOLR-18477
URL: https://issues.apache.org/jira/browse/SOLR-18477
Project: Solr
Issue Type: Improvement
Reporter: Mikhail Khludnev
Assignee: Mikhail Khludnev
There are two hotspots revealed during benchmarking SOLR-18307
* intersection of the cached from-side query and join-column - it should be
adaptive leapfrog instead
* join-index causes a lot of merges, merge spend a lot of time in enumerating
empty stored fields sic - just introduce a codec without stored fields for
auxJoinIdex only
