When the Postgres query planner goes rogue

Everyone’s least favorite alert: nothing changed, everything is on fire. No new deploys, no database failovers, no spike in client query load or inbound requests. Yet suddenly, the database CPU has jumped from 20% utilization to 100% and queries are starting to fail. This is precisely what a customer of ours faced last Thursday. Turns out the root cause is the fickle PostgreSQL query planner, and the solution is Database Traffic Control®. Let’s dig in. An elusive issue When our customer notif

Agents, Workers - Agents can respond to MCP elicitation requests

Agents connected to Model Context Protocol (MCP) servers with addMcpServer can now handle elicitation requests. Elicitation lets an MCP server request user input while it handles a tool call. Form mode collects structured, non-sensitive data. URL mode asks for consent before opening an out-of-band flow, such as third-party authorization or payment. sequenceDiagram participant User participant Agent as Agent (MCP client) participant Server as MCP server participant Browser Se

Markdown for Agents now preserves security- and cache-relevant response headers from your origin when converting HTML to Markdown: Markdown for Agents preserves security headers such as Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Frame-Options, Set-Cookie, and CORS headers (for example, Access-Control-Allow-Origin) on the converted response. Caching headers (Cache-Control, Expires, Age) continue to pass through. Your origin's Content Signals policy is now authoritative. If

R2 - R2 Data Catalog now supports read-only API tokens

R2 Data Catalog now accepts read-only API tokens, so query engines and clients that only read data no longer need a read-write token. Previously, every catalog operation required an Admin Read & Write token, which meant read-only clients were granted more access than they needed. You can now authenticate your Iceberg engine based on your workload: Read-only operations (such as listing namespaces, loading tables, and querying data) work with an Admin Read only token (R2 Data Catalog read and R2 s

R2 Data Catalog, R2 - R2 Data Catalog compaction now optimizes manifest files

R2 Data Catalog, a managed Apache Iceberg catalog built into R2, now automatically optimizes manifest files as part of compaction. Manifest files track the data files that make up an Iceberg table. As a table accumulates many small or fragmented manifests, query engines must read more metadata during query planning, which slows down queries even before any data is scanned. When compaction runs, R2 Data Catalog now rewrites and clusters manifest files by partition as a best-effort pre-step. This
