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 a Volume for instructions.
Once you create the volumes, you 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.
Use these directories to configure the workspaces in the Drill dfs storage plugin configuration.
