Apache Cassandra 5.0 has officially been released, significantly enhancing data management efficiency and introducing AI features and performance optimizations. Key updates include the new Storage-Attached Index (SAI) functionality, allowing for more flexible and efficient non-primary key queries, simplifying the use of secondary indexes, and reducing system load. This version also introduces vector search and vector data types, supporting AI and machine learning projects, enhancing the performance of applications such as recommendations, fraud detection, and image recognition. The unification of compression strategies and the introduction of new data structures further improve data processing.
