Noble Paul created SOLR-14576:
---------------------------------
Summary: HttpCacheHeaderUti.etagCoreCache should not use a
SolrCore as key
Key: SOLR-14576
URL: https://issues.apache.org/jira/browse/SOLR-14576
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Noble Paul
GC performance is affected when the key is a complex data structure. We can
make it
{code}
private static WeakIdentityMap<String, EtagCacheVal> etagCoreCache =
WeakIdentityMap.newConcurrentHashMap();
{code}
instead of
{code}
private static WeakIdentityMap<SolrCore, EtagCacheVal> etagCoreCache =
WeakIdentityMap.newConcurrentHashMap();
{code}
