Noble Paul commented on SOLR-920: --------------------------------- how about an extra attribute in the cores tag to enable sharing as follows. {code:xml} <solr> <cores adminPath="/admin/cores" shareSchema="true"> </cores> </solr> {code} if shareSchema is set to true then for a given path only one instance of IndexSchema is created and it will be shared . It is the responsibilty of the user to ensure that he does not use any core specific properties in the schema.xml when this attribute is set to true > Cache and reuse IndexSchema > --------------------------- > > Key: SOLR-920 > URL: https://issues.apache.org/jira/browse/SOLR-920 > Project: Solr > Issue Type: Improvement > Reporter: Noble Paul > > if there are 1000's of cores then the cost of loading unloading schema.xml > can be prohibitive > similar to SOLR-919 we can also cache the DOM object of schema.xml if the > location on disk is same.
