Set the location of search indexes

Steps to set the location of the search index data on the server.

Data that is added to a DSE Search node is locally indexed on the DSE node. Data changes to one node also apply to the other nodes. DSE Search has its own indexing documents. You can control where the DSE Search indexing documents are saved.
Attention: It is critical that you locate DSE Cassandra transactional data and Solr-based DSE Search data on separate Solid State Drives (SSDs). Failure to do so will very likely result in sub-optimal search indexing performance.
By default, each DSE Search index is saved in solr_data_dir/keyspace_name.table_name, or as specified by the dse.solr.data.dir system property.
Note: The dataDir parameter in the solrconfig.xml file is not supported.

dse.yaml

The location of the dse.yaml file depends on the type of installation:
Package installations /etc/dse/dse.yaml
Tarball installations installation_location/resources/dse/conf/dse.yaml

Procedure

  1. Shut down the search node.
  2. Move the solr.data directory to the new location.
  3. Specify the location:
    OptionDescription
    From the command line To dynamically change:
    cd installation_location && 
bin/dse cassandra -s -Ddse.solr.data.dir=My_data_dir
    In dse.yaml To permanently change:
    solr_data_dir: My_data_dir
    Where My_data_dir is /var/lib/cassandra/solr.data. For example: 
    solr_data_dir: /var/lib/cassandra/solr.data
  4. Start the node.
