I need help regarding hardware configuration of my SolrCloud setup. most of the queries to our SolrCloud are boolean queries involving 6-7 fields and spatial and facet queries. currently for facet queries solr throws OOM errors.
below are my solrcloud stats, solr version 4.6.1 1 collection : 4 shards : each shard has one master and one replica total documents : 700 million total index size is 150 GB, i.e 37.5GB at each shard total fields in index are 30, 25 fields are stored and indexed, remaining are only indexed. hardware of each solr node is quad-core cpu and 16 gb ram JVM parameters : -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -Xms8192M -Xmx8192M Now what we planned is instead of 4 shards we will create 8 shards of 32GB ram and quad-core cpu, then each shard will have ~19GB of index. What will be correct approach here, creating 4 shards with 64 gb ram each or creating 8 shards with 32 gb ram each? -- View this message in context: http://lucene.472066.n3.nabble.com/SolrCloud-performance-issues-regarding-hardware-configuration-tp4147843.html Sent from the Solr - User mailing list archive at Nabble.com.
