Migrate Cassandra workloads to Amazon Keyspaces using CQLReplicator

This article discusses how to migrate Apache Cassandra workloads to Amazon Keyspaces using an open-source utility called CQL Replicator. It provides a step-by-step guide to set up and run CQL Replicator to replicate data from a self-managed Cassandra cluster to Amazon Keyspaces with minimal downtime.

Specifically, the article covers:

• An overview of the CQL Replicator solution and its architecture
• Prerequisites and steps to initialize AWS resources like Amazon S3 and AWS Glue for the migration process
• Configuring and running the CQL Replicator discovery and replication jobs to migrate data from Cassandra to Amazon Keyspaces
• Monitoring the migration process using Amazon CloudWatch metrics
• Sizing recommendations for CQL Replicator based on the size of the Cassandra table being migrated
• Steps to shut down and clean up the CQL Replicator resources after migration
• Conclusion highlighting the benefits of migrating to Amazon Keyspaces and using CQL Replicator for the migration
