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. All the dynamic properties can be replaced lazily
when they are read.
We can go one step ahead in this case. Th IndexSchema object is immutable . So
if there are no core properties then the same IndexSchema object can be used
across all the cores
