Improving read performance

Steps to increase DSE Search read performance.

You can increase DSE Search read performance by increasing the number of replicas. You define a strategy class, the names of datacenters, and the number of replicas. For example, you can add replicas using the NetworkToplogyStrategy replica placement strategy.

Procedure

For example, if you are using a PropertyFileSnitch, perform these steps:

  1. Check the datacenter names of your nodes using the nodetool command.
    nodetool -h localhost ring
    The datacenter names, DC1 and DC2 in this example, must match the datacenter name configured for your snitch.
  2. Start CQL on the command line and create a keyspace that specifies the number of replicas.
    Set the number of replicas in datacenters, one replica in DC1 and three in DC2.
