Step 4: Create Volumes

Volumes organize data and manage cluster performance. Create and mount a volume to each of the topologies (Drill clusters) you created.

For example, you can create a volume named “operational” and mount it to the T1 topology and then create a volume named “analytical” and mount it to the T2 topology.

See Administering Volumes for volume information and Creating Volumes for instructions.

Once you create the volumes, you now have a place where you can create directories and store data. For example, you can create and store operational data in the /operational/data/here directory and analytical data in the /analytical/data/here directory.

The directories in which you store your data are the directories you use to configure the workspaces in the Drill dfs storage plugin configuration.
