Index requirements

The Dgraph requires an index to store the contents of the data sets it can query. All Dgraph nodes in the cluster must be able to connect to the index.

You can install BDD with an existing BDD-formatted index, if you have one you'd like to use. To do this, you must put the index on the NFS before installing and update installer's configuration file to point to the correct directory. For more information, see Updating the configuration file.

If you don't have an existing index, the installer can create an empty one for you. This is also specified in the installer's configuration file.
