Hi everyone, I am running Solr 5.5.0 on HDFS. It is a solrCloud of 50 nodes and I have the following config. maxShardsperNode: 1 replicationFactor: 1
I have been ingesting data into Solr for the last 3 months. With increase in data, I am observing increase in the query time. Currently the size of my indices is 70 GB per shard (i.e. per node). I am using cursor approach (/export handler) using SolrJ client to get back results from Solr. All the fields I am querying on and all the fields that I get back from Solr are indexed and have docValues enabled as well. What could be the reason behind increase in query time? Has this got something to do with the OS disk cache that is used for loading the Solr indices? When a query is fired, will Solr wait for all (70GB) of disk cache being available so that it can load the index file? Thnaks!
