/admin?op=update applies any partial update files to the Dgraph.
This operation instructs the Dgraph to process the partial update files in its update directory. For more information on partial updates, see the Partial Updates Guide.
In some cases, you may need to run a partial update by pointing the Dgraph to a single file. In this case, run the admin?op=update&updatefile=filename option where filename is the name of an update file residing in the update directory.
If you have more than one file, rerun this command. The update file is deleted after the MDEX Engine successfully applies the results of the partial update.
The /admin?op=update operation is not supported in the Agraph.
