[Launched] Generally Available: DiskANN on Azure Database for PostgreSQL

-


I couldn't find specific information about the "Generally Available" status of DiskANN on Azure Database for PostgreSQL or the details from the update link you provided. However, I can give you an overview of DiskANN and its integration with Azure Database for PostgreSQL based on available information.

Overview of DiskANN on Azure Database for PostgreSQL

DiskANN is a powerful vector indexing algorithm developed by Microsoft Research. It is designed to enhance the performance of AI-driven applications by providing advanced vector search capabilities. DiskANN is now available on Azure Database for PostgreSQL - Flexible Server.

Key Features of DiskANN

  • Improved Performance: DiskANN offers superior latency and accuracy compared to existing methods like HNSW and IVFFlat in pgvector[1][3].
  • Scalability: It allows developers to build highly scalable and performant generative AI applications[3].
  • Filtered Vector Search: DiskANN overcomes limitations of pgvector by providing more accurate results in filtered searches[3].

Integration with Azure Database for PostgreSQL

To use DiskANN, users need to:

  • Enable the pgvector and diskann extensions within their PostgreSQL server configuration.
  • Create a table with a vector column to store vector data.
  • Create an index on the vector column using diskann to optimize search performance[1].
CREATE EXTENSION IF NOT EXISTS pg_diskann CASCADE;
CREATE INDEX my_table_embedding_diskann_idx ON my_table USING diskann (embedding vector_cosine_ops);

Use Cases

DiskANN is particularly useful for applications requiring efficient and accurate similarity searches, such as AI-driven applications in image or text processing. It is used in services like Bing and Microsoft 365[3].

Conclusion

DiskANN represents a significant advancement in vector indexing technology, offering enhanced performance and scalability for AI applications on Azure Database for PostgreSQL. However, I couldn't confirm its "Generally Available" status or additional details from the Microsoft update link.

Here is a structured summary of the Generally Available: Private Subnet launch announcement and key information from the official Azure Updates page referenced (https://azure.microsoft.com/updates?id=492953): General Availability of Azure Private Subnet Announcement Date: May 2025[1] Feature Status: Launched (now generally available for all Azure customers) Description: The "private subnet" feature for Azure Virtual Network is now production-ready, enabling customers to create subnets with enhanced network isolation and security. Key Benefits: Enhanced Security: Private subnets help restrict outbound internet access, reducing the risk of unauthorized data exfiltration. Explicit Internet Access: VMs in a private subnet do not have default outbound internet access, requiring explicit configuration of NAT gateways or other routes for connectivity[5]. Greater Control: Organizations gain more granular management over their Azure VM network traffic, allowing them t...
