Frequently asked question about {{ DC }} {{ data-transfer-name }}

Questions:

• Does {{ data-transfer-name }} support encryption?
• Can I transfer empty tables in {{ data-transfer-name }}?
• Do you support changing the schema after activating a transfer?

Does {{ data-transfer-name }} support encryption? {#encryption-support}

If a {{ DC }} cluster (source or target) has encryption enabled, {{ data-transfer-name }} will support this encryption.

Can I transfer empty tables in {{ data-transfer-name }}? {#empty-tables}

{{ data-transfer-name }} doesn't support transfer of empty tables or other empty entities.

There's an exception — in homogeneous transfers, you can copy metadata separately. In this case, empty tables and other entities (views, triggers, etc.) will be transferred.

Do you support changing the schema after activating a transfer? {#schema-change-after-activation}

Some transfer target support on-flight schema changes (such as Clickhouse)
