Qdrant 1.2 introduces several new features and improvements, focusing on performance and reliability in its vector database. The release includes the introduction of Product Quantization, which significantly reduces memory requirements, and optional named vectors, allowing for nullable vectors to enhance flexibility. Additionally, it features a new mechanism for grouping requests, enabling client-side operations to be handled server-side, and improved nested filtering capabilities for more complex data queries. The update also addresses reliability with a recovery mode to tackle memory constraints and appending capabilities for mmap storage. Security enhancements include API-key support for authentication and TLS support for encrypted connections. The Qdrant team encourages feedback from its community to continue shaping the platform's development.
