It's been a while since the terminology at http://wiki.apache.org/solr/SolrTerminology has been updated, so I'm wondering how these terms apply to solr cloud setups.
My take on what the terms mean: Collection: Basically the highest level container that bundles together the other pieces for servicing a particular search setup Core: An individual solr instance (represents entire indexes) Shard: A portion of a core (represents a subset of an index) Therefore: - increasing the number of shards allows for indexing more documents (aka scaling the amount of data that can be indexed) - increasing the number of cores increases the potential throughput of requests (aka cores mirror each other allowing you to distribute requests to multiple servers) Does this sound right? If so, then my follow up question would be does the following directory structure look right/standard? .../solr # = solr home .../solr/collection-01 .../solr/collection-01/core-01 .../solr/collection-01/core-02 And if this is right, I'm on a roll :D My next question would then be: Given we're using zookeeper (separate machine), do we need 1 conf folder at collection-01's level? Or do we need 1 conf folder per core? -- View this message in context: http://lucene.472066.n3.nabble.com/Cloud-terminology-clarification-tp4006407.html Sent from the Solr - User mailing list archive at Nabble.com.
