Hi,
We have some custom code that extends SearchHandler to be able to :
- do an extra request
- merge/combine the original request and the extra request results
On Solr 5.x, our code was working very well, now with Solr 6.x we
have the following issue: the number of SolrIndexSearcher are
increasing (we can see them in the admin view > Plugins/ Stats > Core ).
As SolrIndexSearcher are accumulating, we have the following issues :
- the memory used by Solr is increasing => OOM after a long
period of time in production
- some files in the index has been deleted from the system but
the Solr JVM still hold them => ("fake") Full disk after a long period
of time in production
We are wondering,
- what has changed between Solr 5.x and Solr 6.x in the
management of the SolrIndexSearcher ?
- what would be the best way, in a Solr plugin, to perform 2
queries and merge the results to a single SolrQueryResponse ?
Thanks a lot.
Gérald, Elodie, Ludo and André
