What is QuestDB?

QuestDB 10.0 ships QWP — a binary protocol unifying ingestion and Arrow reads — while Enterprise 4.0 adds cold storage and hot failover.

QuestDB landed two major releases back to back: 10.0 (open source) and Enterprise 4.0. The central innovation in both is QWP — a binary, columnar wire protocol that handles both data writes and Apache Arrow reads over a single client connection. Enterprise 4.0 layers cold storage on top, aging partitions to object storage while keeping them queryable, and adds hot failover without a restart. The benchmarks are real: 33M rows/s against ILP, 500M rows streamed to Arrow in 2.3 seconds.

What is Sanity?

Sanity's MCP server now advertises itself to agents through a server card and llms.txt.

Sanity shipped three MCP server releases in two days. 2.44.0 makes the server discoverable through a /.well-known server card, an HTML or markdown landing page, robots.txt and llms.txt, and cuts CPU per request. 2.43.0 adds an undeploy_schema tool and deprecates workspaceName for schema selection. 2.42.2 fixes validation against deployed schemas and refuses patches that would change a document's _type.

QuestDB 10.0 ships QWP — a binary protocol unifying ingestion and Arrow reads — while Enterprise 4.0 adds cold storage and hot failover.

◆ Current state

QuestDB landed two major releases back to back: 10.0 (open source) and Enterprise 4.0. The central innovation in both is QWP — a binary, columnar wire protocol that handles both data writes and Apache Arrow reads over a single client connection. Enterprise 4.0 layers cold storage on top, aging partitions to object storage while keeping them queryable, and adds hot failover without a restart. The benchmarks are real: 33M rows/s against ILP, 500M rows streamed to Arrow in 2.3 seconds.

◆ Where it's heading

QuestDB is positioning itself as the time-series database that fits into modern lakehouse architectures without requiring ETL. QWP + Arrow + cold storage + Iceberg compatibility all point toward a single goal: a streaming time-series engine that speaks natively to Parquet-based analytics stacks. The blog post explaining Parquet/Iceberg positioning is the clearest signal — the team is selling to data engineers building lakehouses, not just ops engineers running dashboards.

◆ Prediction

The cold storage Iceberg integration will deepen with catalog support and query pushdown for Spark and Trino. QWP client libraries will ship for major languages beyond the initial Python/Java coverage.

5.0

Sanity's MCP server now advertises itself to agents through a server card and llms.txt.

◆ Current state

Sanity shipped three MCP server releases in two days. 2.44.0 makes the server discoverable through a /.well-known server card, an HTML or markdown landing page, robots.txt and llms.txt, and cuts CPU per request. 2.43.0 adds an undeploy_schema tool and deprecates workspaceName for schema selection. 2.42.2 fixes validation against deployed schemas and refuses patches that would change a document's _type.

◆ Where it's heading

The MCP server is becoming the main way agents read and write Sanity content, and the work has shifted from adding tools to making it safe and findable: guarded patches, accurate safety annotations, full schema lifecycle and discovery metadata. Studio and Manage continue alongside it with speed work and admin features for larger organizations.

◆ Prediction

Expect workspaceName to be removed after the migration period, and more guardrails on write tools such as patch_documents.
