Configuring Metadata Storage

Prerequisites​

Disk size requirements for base and high availability configurations are on the System Requirements page.

Default Location​

The default location for metadata storage is the ${DREMIO_HOME}/data directory.

  • For an RPM installation, the default metadata storage location is create for you at /var/lib/dremio, however, you can change this location by setting up a custom location.
  • For a Tarball installation, manually create the directory and add the location to the dremio.conf file. It is recommended that you use the default: /data/dremio

Configuration​

To customize metadata storage configuration, modify the paths.local property. To setup a custom metadata storage location:

  1. Create your custom directory if it doesn't exist, for example: /data/customDremio

    Creating metadata store directory 
    sudo mkdir /data/customDremio && sudo chown dremio:dremio /data/customDremio

  2. Add the new location to the dremio.conf file in the local field under paths. This is done in the dremio.conf file on the coordinator nodes(s) only.

    Metadata location 
    paths: {
      local: "/data/customDremio"
    }
