Migrating to Amazon Keyspaces - Amazon Keyspaces (for Apache Cassandra)

Migrating to Amazon Keyspaces

Amazon Keyspaces (for Apache Cassandra) is a scalable, highly available, and managed Apache Cassandra–compatible database service. You can migrate your data to Amazon Keyspaces from Cassandra databases running on premises or on Amazon Elastic Compute Cloud (Amazon EC2) by using the steps in this section.

We recommend that you follow these best practices to ensure that your migration is successful:

  • Break the migration down into smaller components.

    Consider the following units of migration and their potential footprint in terms of raw data size. Migrating smaller amounts of data in one or more phases may help simplify your migration.

    By cluster – Migrate all of your Cassandra data at once. This approach may be fine for smaller clusters.

    By keyspace or table – Break up your migration into groups of keyspaces or tables. This approach can help you migrate data in phases based on your requirements for each workload.

    By data – Consider migrating data for a specific group of users or products, to bring the size of data down even more.

  • Prioritize what data to migrate first based on simplicity.

    Consider if you have data that could be migrated first more easily—for example, data that does not change during specific times, data from nightly batch jobs, data not used during offline hours, or data from internal apps.

  • Use specific tooling.
