Hi!
I would like to contribute a more granular NRT implementation as to
soft-commit (enabled with the realtime tag). This does not close the
SolrIndexSearcher instances but keeps passing the NRT reader as a
parameter to the searcher maintaining the searcher paradigm of being
lean and stateless. Everything works as before if realtime is not
enabled. With realtime enabled, the reader passed to the searcher is an
NRT enabled reader allowing the most recent docs to be found. Since a
reader is passed as a parameter the need to close and create a
SolrIndexSearcher object is not needed and so the caches structures in
SolrIndexSearcher do not need to be invalidated. SolrIndexSearcher is a
heavy object, not closing/creating a new one, including the caches leads
to improved NRT performance.
Do I need to make a patch or should I open a JIRA and attach the source
to the JIRA ?
