One-Step Streaming Migration from DynamoDB into ScyllaDB

The blog post discusses the process of migrating data from Amazon DynamoDB to ScyllaDB using the ScyllaDB Migrator tool, which now includes live replication capabilities. This new feature leverages DynamoDB Streams, introduced in 2014, to capture and replicate table modifications in real-time using Spark Streaming. The process involves an initial snapshot transfer of the source table, after which the migrator consumes the DynamoDB Stream to apply continuous changes to the ScyllaDB table, ensuring no data loss and eventual synchronization between the source and target tables. The post provides a detailed walkthrough of configuring the migration process, highlighting the necessary steps and resources needed to complete it within DynamoDB Streams' 24-hour retention limit. Additionally, it demonstrates a test run using a load generation tool to validate the functionality, confirming that the contents of both the source and target tables remain identical after migration.
