Adding, decommissioning, repairing a node
About adding, removing, or repairing a Solr node.
To increase the number of nodes in a Solr cluster, you can add a DSE node to the cluster. If you want to increase capacity of your search, add the node, then optionally, rebalance the cluster. To add a Solr node, use the same method you use to add a Cassandra node. Using the default DSESimpleSnitch automatically puts all the Solr nodes in the same data center. Use OpsCenter Enterprise to rebalance the cluster.
You can decommission and repair a Solr node in the same manner as you would a Cassandra node. The efficient and recommended way to repair a node, or cluster, is to use the subrange repair method.
