Migrating from DynamoDB to ScyllaDB’s DynamoDB-compatible API

ScyllaDB has introduced Project Alternator, an open-source tool that ensures API-level compatibility with Amazon DynamoDB, allowing users to migrate their data seamlessly to ScyllaDB without altering client code. This initiative expands the capabilities of the ScyllaDB Migrator, originally designed for Apache Cassandra, by enabling data transfer from DynamoDB to ScyllaDB using Apache Spark-based parallel processing. The migration process involves configuring source and target settings, submitting the Spark application, and adjusting throughput variables to suit provisioned resources, which can be monitored via the Spark web UI. The successful data migration is verified by matching key counts and conducting random key queries across both databases. Future updates aim to incorporate DynamoDB's stream interfaces to facilitate live migrations without downtime, and a webinar is scheduled to provide more insights into Project Alternator.
