The Apache Software Foundation (ASF) has announced Apache Cassandra 5.0, which introduces new features and improvements that enhance its capabilities for modern, data-intensive applications.

Cassandra is an open source, highly performant, distributed database management platform. As a NoSQL database, Apache Cassandra handles massive amounts of data across load-intensive applications with high availability and no single point of failure. Cassandra’s largest production deployments include Apple, Netflix, Huawei, Walmart, and numerous other organizations worldwide.

“Apache Cassandra 5.0 represents a significant leap forward in distributed database technology,” said Dinesh Joshi, Vice President of Apache Cassandra and Project Chair. “This release brings groundbreaking features that enhance performance and scalability and position Cassandra at the forefront of AI-driven data management.”

Cassandra 5.0 brings new features and enhancements designed to elevate its performance for modern, data-intensive applications. Key highlights include:

• Storage Attached Indexes (SAI): Revolutionizes query flexibility and performance, especially for large datasets, allowing for more efficient and versatile data retrieval.
• Trie Memtables and Trie SSTables: Optimizes memory and storage usage, significantly improving database performance without requiring changes to existing data models.
• Unified Compaction Strategy (UCS): Enhances operational efficiency by automatically adapting to changing requirements, reducing manual intervention in data organization.
• Vector Search: Introduces native support for artificial intelligence (AI) and machine learning applications, enabling semantic search capabilities crucial for next-generation applications.
• JDK 17 Support: Upgrades to Java Development Kit 17, bringing substantial performance improvements and new language features.
• Dynamic Data Masking: Enhances data security by allowing sensitive information to be obscured dynamically during queries without altering the stored data.
• Mutual TLS Authentication: Brings certificate based authentication and authorization to Apache Cassandra allowing the users to authenticate with no passwords required.
