Use Astra DB Sideloader with ZDM Proxy
Astra DB Sideloader is a service running in Astra DB that imports data from snapshots of your existing Cassandra-based cluster. This tool is exclusively for migrations that move data to Astra DB.
Because it imports data directly, Astra DB Sideloader can offer several advantages over CQL-based tools like DSBulk Migrator and Cassandra Data Migrator, including faster, more cost-effective data loading, and minimal performance impacts on your origin cluster and target database.
Migrate data with Astra DB Sideloader
To migrate data with Astra DB Sideloader, you use nodetool, a cloud provider’s CLI, and the Astra DevOps API:
-
nodetool: Create snapshots of your existing DSE, HCD, open-source Cassandra cluster. For compatible origin clusters, see Astra Migration Toolkit. -
Cloud provider CLI: Upload snapshots to a dedicated cloud storage bucket for your migration.
-
Astra DevOps API: Run the Astra DB Sideloader commands to write the data from cloud storage to your Astra DB database.
For more information and instructions, see About Astra DB Sideloader.
Use Astra DB Sideloader with ZDM Proxy
You can use Astra DB Sideloader alone or with ZDM Proxy.
If you need to migrate a live database, you can use Astra DB Sideloader instead of DSBulk Migrator or Cassandra Data Migrator during of Phase 2 of Zero Downtime Migration.
