Set the location of search indexes

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.

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.

The dataDir parameter in the solrconfig.xml file is not supported.

Procedure

Shut down the search node.
Move the solr.data directory to the new location.

Specify the location:

Option Description

Option	Description
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`

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

Start the node.
