Noble Paul commented on SOLR-14985: ----------------------------------- We need to cache the data longer. There is no reason why we should not cache the data longer. (both alias and state.json) > Slow indexing and search performance when using HttpClusterStateProvider > ------------------------------------------------------------------------ > > Key: SOLR-14985 > URL: https://issues.apache.org/jira/browse/SOLR-14985 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level. Issues are Public) > Components: SolrJ > Reporter: Shalin Shekhar Mangar > Priority: Major > > HttpClusterStateProvider fetches and caches Aliases and Live Nodes for 5 > seconds. > The BaseSolrCloudClient caches DocCollection for 60 seconds but only if the > DocCollection is not lazy and all collections returned by > HttpClusterStateProvider are not lazy which means they are never cached. > The BaseSolrCloudClient has a method for resolving aliases which fetches > DocCollection for each input collection. This is an HTTP call with no caching > when using HttpClusterStateProvider. This resolveAliases method is called > twice for each update. > So overall, at least 3 HTTP calls are made to fetch cluster state for each > update request when using HttpClusterStateProvider. There may be more if > aliases are involved or if more than one collection is specified in the > request. Similar problems exist on the query path as well. > Due to these reasons, using HttpClusterStateProvider causes horrible > latencies and throughput for update and search requests. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
