ASF subversion and git services commented on SOLR-6832: ------------------------------------------------------- Commit 1659750 from [~thelabdude] in branch 'dev/branches/branch_5x' [ https://svn.apache.org/r1659750 ] SOLR-6832: Queries be served locally rather than being forwarded to another replica > Queries be served locally rather than being forwarded to another replica > ------------------------------------------------------------------------ > > Key: SOLR-6832 > URL: https://issues.apache.org/jira/browse/SOLR-6832 > Project: Solr > Issue Type: Bug > Components: SolrCloud > Affects Versions: 4.10.2 > Reporter: Sachin Goyal > Assignee: Timothy Potter > Fix For: Trunk, 5.1 > > Attachments: SOLR-6832.patch, SOLR-6832.patch, SOLR-6832.patch, > SOLR-6832.patch > > > Currently, I see that code flow for a query in SolrCloud is as follows: > For distributed query: > SolrCore -> SearchHandler.handleRequestBody() -> HttpShardHandler.submit() > For non-distributed query: > SolrCore -> SearchHandler.handleRequestBody() -> QueryComponent.process() > \\ > \\ > \\ > For a distributed query, the request is always sent to all the shards even if > the originating SolrCore (handling the original distributed query) is a > replica of one of the shards. > If the original Solr-Core can check itself before sending http requests for > any shard, we can probably save some network hopping and gain some > performance. > \\ > \\ > We can change SearchHandler.handleRequestBody() or HttpShardHandler.submit() > to fix this behavior (most likely the former and not the latter). -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
