<p><strong>TLDR:</strong> Microsoft used FabCon and SQLCon 2026 to announce Database Hub, a single management interface pulling Azure SQL, Cosmos DB, PostgreSQL, MySQL, and more under one roof inside Fabric. SingleStore 9.1 ships a native F16 vector type that cuts storage roughly in half and speeds up exact kNN queries by about 38%. MongoDB Atlas added direct log streaming to Datadog, Splunk, S3, and any OpenTelemetry endpoint. Hibernate Search 8.3 is out, aligning with Hibernate ORM 7.3 and Elasticsearch 9.3.</p>

<h2>Microsoft Fabric Database Hub</h2>
<p>Database Hub is now in early access inside Fabric, consolidating Azure SQL, Cosmos DB, PostgreSQL, MySQL, SQL Server via Arc, and other Fabric services into one management interface. The pitch is straightforward: stop jumping between five portals to understand what your databases are doing. Microsoft is layering agent-assisted monitoring and Copilot-driven performance insights on top. A few other concrete updates landed alongside it: SQL database in Fabric added SQL Auditing, Customer-Managed Keys, and Dynamic Data Masking; Azure SQL Hyperscale gets 160 and 192 vCore options plus improved vector indexing; and GitHub Copilot in SSMS 22 is now generally available. OneLake also picked up new shortcuts for Oracle, SAP Datasphere, and Snowflake.</p>
<h2>SingleStore 9.1 F16 vector type</h2>
<p>SingleStore 9.1 introduces <code>VECTOR(&lt;N&gt;, F16)</code>, a native 16-bit float storage type for embeddings. On the GIST 1M benchmark, F16 cuts storage from 3.58GB to 1.79GB and speeds up exact kNN by roughly 38% compared to F32, with recall staying in the 96-98% range. ANN index search also improves slightly from better cache utilization. For most semantic search and RAG workloads the precision trade-off is negligible; the post notes F32 still makes sense for finance or medical imaging where precision matters more.</p>
<h2>MongoDB Atlas log integration with OpenTelemetry</h2>
<p>MongoDB Atlas now streams mongod, mongos, and audit logs directly to Datadog, Splunk, Google Cloud Storage, Azure Blob, Amazon S3, or any OpenTelemetry-compatible endpoint. It targets M10+ dedicated clusters and can be configured via the Atlas UI or Terraform. The main practical win here is audit log routing to long-term storage without building a custom pipeline, plus unified telemetry correlation when you already have metrics flowing through an existing observability stack.</p>
<h2>Hibernate Search 8.3 released</h2>
<p>Hibernate Search 8.3.0.Final is out and is essentially the CR1 candidate with dependency bumps: Hibernate ORM 7.3.0.Final, Elasticsearch 9.3 with client 9.3.2, OpenSearch 3.4/3.5 with client 3.5.0, Lucene 10.4.0 for the Lucene-next backend, and AWS SDK 2.42.14. It’s a drop-in replacement for 8.2 as long as you upgrade the dependencies alongside it.</p>

<li><strong>Snowflake Cortex Agent version control:</strong> A practical walkthrough shows how to extract agent specs into dbt models with custom materializations, getting full Git history, PR-based prompt review, and reproducible multi-environment deployments via dbt’s <code>ref()</code>.</li>
<li><strong>Microsoft Fabric Migration Assistant (preview):</strong> Migrates on-premises SQL Server to SQL database in Fabric via DAC pack for schema and a Copy Job for data; current cap is 20MB DAC pack files supporting roughly 100k objects.</li>
<li><strong>Snowflake SF-Managed Iceberg:</strong> Part 4 of the Snowflake/Databricks interoperability series covers the pattern where Snowflake owns the full Iceberg lifecycle while writing open Parquet to your own storage, with external engines reading back via the Horizon Catalog REST API.</li>
<li><strong>FalkorDB vs relational DBs:</strong> FalkorDB uses GraphBLAS to represent graph traversals as sparse matrix operations, giving sub-millisecond latency on deep multi-hop queries where recursive CTEs fall apart; it speaks openCypher and integrates with Snowflake as a Native App.</li>
<li><strong>Meta Reels pipeline efficiency:</strong> An engineer from the Instagram Reels team describes megawatt-scale energy savings through lazy logging, batched storage schemas (cutting storage 40%), and removing thousands of statistically insignificant features rather than touching model architecture.</li>
<li><strong>DuckDB.ExtensionKit:</strong> An experimental MIT-licensed toolkit lets C# developers build native DuckDB extensions using .NET APIs, compiled via AOT to a platform-native binary with no managed runtime dependency.</li>
<li><strong>Supabase + Stripe Projects:</strong> Supabase joined the Stripe Projects developer preview; one CLI command provisions a full Supabase stack (Postgres, Auth, Storage, Edge Functions, Realtime) with credentials written to <code>.env</code>, designed to work for AI agents that can’t interact with browser dashboards.</li>
<li><strong>Datadog Go binary size:</strong> Datadog achieved a 77% reduction in Go binary sizes, mentioned in the Technology Short Take 192 link roundup alongside Kubernetes Gateway API support in the AWS Load Balancer Controller.</li>
