Cosmos DB introduces an agent memory toolkit as a Python SDK for storing and retrieving short-term and long-term agent memories using change feed and Azure Durable Functions. Azure SQL gets a new local container for offline-first development with vector hybrid search, MCP endpoints via Data API Builder, and local AI model inference. The headline announcement is Azure Horizon DB, a new PostgreSQL service with separated compute and storage delivering ~3x transactional throughput over self-managed Postgres, plus AI pipelines (via pg_durable extension) for async chunking and embedding generation, AI model management with pre-registered Foundry models, DiskANN vector indexing, and deep VS Code tooling including visual query plans with Copilot integration. ## Full article daily.dev links to this article rather than hosting it.
