What is PlanetScale?

PlanetScale is giving Postgres users budgets, guardrails, and a read-only door for agents.

The changelog is dominated by Postgres reaching parity with, and then past, the Vitess side of the platform. Database Traffic Control introduced resource budgets for query traffic, with warning thresholds before enforced budgets bite; storage became configurable at database creation; the vectorscale extension landed; and a new GCP region opened in Eemshaven. Query Insights gained negated search terms across both engines, and an Insights-only variant of the MCP server shipped without query execution tools.

What is Knock?

Notification infrastructure grows a memory: workflows can now wait on the real world.

Knock sells notification infrastructure — workflows, broadcasts, in-app guides, and multi-channel delivery that product teams wire up instead of building themselves. July was dense and unusually broad: a rebuilt Notion-style template editor, saved views and tags, schema management for how properties surface across the dashboard, passkey login, branch rebasing, and sandbox test runs that skip delay steps. Underneath the polish, two structural additions landed — message events syncing into the data warehouse, and a workflow step that pauses until an event arrives.

PlanetScale is giving Postgres users budgets, guardrails, and a read-only door for agents.

◆ Current state

The changelog is dominated by Postgres reaching parity with, and then past, the Vitess side of the platform. Database Traffic Control introduced resource budgets for query traffic, with warning thresholds before enforced budgets bite; storage became configurable at database creation; the vectorscale extension landed; and a new GCP region opened in Eemshaven. Query Insights gained negated search terms across both engines, and an Insights-only variant of the MCP server shipped without query execution tools.

◆ Where it's heading

PlanetScale is building the operational controls that decide whether a managed database is safe to hand to a large team. Traffic budgets, warning thresholds, storage checks before deploy requests and connection-level guardrails all address the same failure mode: one workload consuming the cluster. The Insights-only MCP variant applies that instinct to agents — give them observability and schema recommendations, withhold the ability to execute queries.

◆ Prediction

Expect Traffic Control to gain more granularity and for the Postgres offering to keep closing extension and region gaps. The scoped MCP server suggests further work on what agents are allowed to do rather than simply exposing more of the platform to them.

Notification infrastructure grows a memory: workflows can now wait on the real world.

◆ Current state

Knock sells notification infrastructure — workflows, broadcasts, in-app guides, and multi-channel delivery that product teams wire up instead of building themselves. July was dense and unusually broad: a rebuilt Notion-style template editor, saved views and tags, schema management for how properties surface across the dashboard, passkey login, branch rebasing, and sandbox test runs that skip delay steps. Underneath the polish, two structural additions landed — message events syncing into the data warehouse, and a workflow step that pauses until an event arrives.

◆ Where it's heading

The developer-workflow half of the product is being treated like a codebase: branches that rebase onto main, tests that run in sandbox without delivering, tags and saved views for navigating a growing workspace. The engine half is moving in a different direction — toward workflows that hold state over time. A wait-for-event step, combined with the Clay data source triggering messaging as rows finish enriching, describes journeys rather than notifications. The analytics work is arriving twice over: raw events into the warehouse for teams with their own stack, and natural-language questions to the Knock agent for teams without one.

◆ Prediction

Wait-for-event is the primitive that makes journey-shaped use cases possible, so expect the next releases to address what it exposes — timeouts, observability into workflows sitting paused, and limits on how long one can wait before it becomes a support problem.
