Hi,
After upgrading solr from 3.6 to 4.3, we found that solr opened a lot more
files compared to
solr 3.6 (when core is open). Since we have many cores (more than 2K and still
grow), we
would like to reduce the number of open files.
We already used shareSchema and sharedLib, we also shared SolrConfig across all
cores,
we also commented out autoSoftCommit in solrconfig.xml.
In solr 3.6, it seems that indexWriter is opened only if indexing request comes
and immediately
closed after request is done, but in solr 4.3, IndexWriter kept open, is there
an easy way to
go back to 3.6 behavior (we donot need to use Near RealTime Search), can we
change code
to disable keeping IndexWriter open (if no better way)?
Any guidance to reduce open files would be very helpful?
Thanks very much for helps, Lisheng
