Migration

VeloDB Cloud provides an efficient, secure, one-stop data migration function. Use it to move full data from Apache Doris, VeloDB, or StarRocks into a VeloDB Cloud warehouse.

Open Migration from the Work with data group in the left navigation, then click Create Migration Task to start.

1. Connect to the source cluster​

Fill in the task name and description, then enter the source cluster's connection details: JDBC port, HTTP port, username, and password. Click Next to verify connectivity.

2. Configure temporary object storage​

Pick an object-storage provider and fill in the bucket address and authorization information. VeloDB Cloud uses this bucket as a temporary staging area during migration and cleans it up automatically after the task finishes.

3. Select databases and tables​

Pick the databases and tables to migrate. You can select them in batches or use custom filters. You can also add row-level data filters for each table.

4. Set migration resources​

Choose the cluster that will perform the migration, and set the concurrency:

  • Table concurrency — how many tables migrate in parallel.
  • Tablet concurrency per table — how many tablets of a single table migrate in parallel.
