Supercharge your Apache Cassandra Data Model with Storage-Attached Indexing (SAI)

This fourth part of a six-part series on Apache Cassandra introduces Storage-Attached Indexing (SAI) features on DataStax Astra DB, a managed Cassandra-as-a-database-service on the cloud. The text discusses indexing in both relational and Cassandra databases, explaining how secondary indexes work compared to distributed indexing like tables and materialized views. It also covers the limitations of secondary indexing practices and introduces DataStax's SAI as a solution that provides efficient secondary indexing for Astra DB and Cassandra. The text concludes with setting up Astra DB to create a fully-realized Cassandra database and query outside of primary keys through SAI, along with examples of use cases like client data modeling and IoT applications.
