Manage metadata migrations

Manage your metadata migrations with Data Migrator using either the UI or CLI.

Manage metadata migrations with the UI

The Dashboard displays an overview of metadata migrations and their status, showing what metadata has been transferred and added since the migration started.

For an overview of the progress and status of individual metadata migrations, go to the Metadata Migrations panel, and search for or filter migrations by migration name.

Status

Select a migration from the Dashboard, Metadata Migrations panel to view its current state, to pause, stop, resume, or delete a migration and view objects migrated information.

note

The object counts displayed on the Metadata Migration Status page show the number of actions taken on the target by Hivemigrator. This includes: creation of databases, tables, views and partitions; changes to write ids and responses to events received from Hive on the source.

Pause a metadata migration

When you start a metadata migration, you can select Pause to suspend transferring metadata.

You can resume a metadata migration that is paused.

Stop a metadata migration

Once a metadata migration has started, you can select Stop to suspend transferring metadata.

You can resume a metadata migration that is stopped.

Resume a metadata migration

note

See Manage metadata changes for more information on Listening mode.

Resume a paused metadata migration

You can select Resume on a paused migration. If Listening mode is enabled, the migration continues to process the events provided by the listener. If listeners aren't configured, the migration restarts scanning for changes.

Resume a stopped metadata migration

You can select Resume on a stopped migration. If Listening mode is enabled, the migration scans once for changes before continuing to process the events provided by the listener. If listeners aren't configured, the migration restarts scanning for changes.

Delete a metadata migration

You must stop or pause a metadata migration before you can delete it.

To delete a metadata migration:

Select the metadata migration from your Metadata Migrations panel.
On the Migration Status page, select Stop.
Select Delete.

You can apply Resume, Start, and Stop actions to multiple metadata migrations at once with the UI. See Bulk actions for more details.
