Introducing Cassandra-compatible APIs in Spanner for zero-code-change migration

  • Google Cloud introduced native support for the Cassandra Query Language (CQL) API in Spanner to aid in zero-code-change application migration.
  • The migration from Cassandra to Spanner typically involves minimal code changes, with new data migration tools for seamless transition.
  • Reasons to migrate include addressing Cassandra's high TCO, performance issues with secondary indexes, and limitations in CQL functionality.
  • Spanner offers advantages like simplified operations, elastic scalability, global ACID transactions, and strongly consistent global secondary indexes.
  • The migration process involves setting up Spanner, converting schemas, migrating data, validating data integrity, and switching applications to use the native endpoint.
  • Spanner provides cost-effectiveness through managed service, usage-based billing, elastic scaling, and tiered storage options.
  • A Forrester Consulting study revealed Spanner delivered a 132% ROI and $7.74 million in benefits over three years for customers.
  • Moving to Spanner opens up opportunities for building new microservices, implementing graph queries, and integrating with BigQuery for analytics.
  • Integration of Google Cloud Spanner with Cassandra-compatible APIs enables modernization of data workloads on Google Cloud.
  • Google Cloud offers a migration kit and free trial to assist in transitioning Cassandra applications to Spanner for enhanced capabilities.
