Tutorial: Cassandra Migration to Astra DBaaS

The text discusses the process of migrating a multi-cloud Database-as-a-Service (DBaaS) for Apache Cassandra® applications called Astra. It mentions that portions of the architecture and tooling backing it are open-sourced, and users can migrate their first Cassandra application to Astra for free. The migration process is outlined in four steps: creating a corresponding table in the destination cluster, downloading access credentials as a secure connect bundle, starting Spark with the Spark Cassandra Connector, reading data from the source cluster using DataFrame API, and writing data to the destination cluster. The text also mentions that users can use RDD API for migration but it is more verbose. It concludes by encouraging users to try migrating their existing database to DataStax Astra using Spark Cassandra Connector 2.5.1 with Apache Spark, and assures help from the DataStax team if needed.
