How many cores can solr support

Return to Frequently Asked Questions. Specific best practices for nodes, shards, and replicas are presented below. Best Practice: Use at least two nodes! Best Practice: Use one shard! Best Practice: One replica per node! My question: is this architecture a correct use case for Solr multiple cores? Anyone have some suggests? It also allows you to distribute your data on multiple machines. It will also make your performance better, querying would be much easier and you could add multiple collections with different schema's too.

Generally cores are created to differentiate the application data in different collection entity format. It generally becomes useful to migrate core data from lower version to higher version.

You can have many cores in solr. Suppose you have data harvested from two different source like one from X source and other from Y source, we generally would store them in 2 separate cores. In your case it would be good idea to have 2 cores over same set of collection of data as the memory limit is huge.

Generally a single core can accommodate huge amount memory. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Then dataDir is not properly configured. Make sure that you defined the correct dataDir in the solr. You can of course follow these instructions again to setup further Solr cores. Creating new index Question: As per my knowledge Solr handles one request at a time. Is there any problem in having multiple Solr instances running at different ports?

This is pretty interesting, is your Solr setup configured as SolrCloud or plain single Solr with multiple cores?
