--------------------------------------
Summary: Colocated cores with the same configset should share
resources
Key: SOLR-16615
URL: https://issues.apache.org/jira/browse/SOLR-16615
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Jason Gerlowski
Currently, each core parses solrconfig.xml and instantiates its own copy of
various plugins (v2 'Api' instances, RequestHandlers, etc.) or plugin-related
objects (e.g. Jersey "ApplicationHandlers").
Usually this is fine, but when many cores on a Solr node share the same
configset, this duplication can become wasteful and have considerable impacts
on node startup and core reload time.
We should investigate whether some of these solrconfig.xml-driven entities can
be shared by cores with the same configset that live in the same JVM.
