Rebecca Mills guest edits an issue on DataStax Developer Learning, focusing on the new Storage Attached Index (SAI) in Cassandra. SAI addresses previous indexing challenges such as write amplification and index size on disk. It is designed to use less disk space and supports faster writes than other indexes. SAI is available in DataStax Enterprise 6.8.3, with a hands-on learning experience provided through the new Cassandra Indexing Skills Page. DataStax has submitted the Apache CEP for bringing this functionality to the Apache version of Cassandra and encourages feedback from users. The company's Chief Strategy Officer, Sam Ramji, hosts a podcast series called Open||Source||Data exploring open-source data and related topics.
