Adding, decommissioning, repairing a DSE search node Steps to add, decommission nodes, and repair DSE search nodes. To add, decommission, or repair a DSE Search node, use the same methods as you would for a Cassandra node. Procedure To increase the number of DSE Search nodes in a datacenter, add a search node to the cluster, and then use OpsCenter to rebalance the cluster. The default DSESimpleSnitch automatically puts the DSE Search nodes in the same data center. To repair a DSE Search node, see Repairing nodes in the Cassandra documentation. DataStax recommends using the subrange repair method. To decommission a DSE Search node, see Removing a node in the Cassandra documentation. To plan DSE Search hardware requirements, see Search node capacity.
