[jira] Commented: (SOLR-1277) Implement a Solr specific naming service (using Zookeeper)

[jira] Updated: (SOLR-1197) memcached implement solr cache for queryresultCache

Linbin Chen updated SOLR-1197:
--
Attachment: SOLR_1197-solr-memcache-0.2.patch
solr sint hashcode conflict cause solr memcached bug
solr-memcached-0.2
solr sint fieldType sint.hashcode conflict very hight above 99%
such as id:44232808 and id:44090533 hashcode conflict, so q=id:44232808
maybe response id:44090533 doc result. error!
http://code.google.com/p/solr-side/issues/detail?id=2&can=1
solr-memcached-0.2 patch for create memcache key strategy:
QueryResultKey add method
public String toString() {
return query.toString();
}
for MemcachedCache md5(QueryResultKey.toString())
now memcache key strategy =
md5(keyPrefix+indexVersion+QueryResultKey.hashCode()+md5(QueryResultKey.toString()))
double md5
