Diagrid releases Dapr 1.19 with less data for each agent step

Diagrid, a company that makes agent infrastructure, released Dapr 1.19 on 9 November 2026. Dapr is an open-source runtime that operates long tasks for AI agents. The new version sends less data for each step of a long task. Users can also remove one of 2 control-plane services. The numbers come from tests by Diagrid.

How it works

Before 1.19, the workflow engine sent the full history of a task to the worker at each step. The history has more data at each step. Diagrid tells that this caused more latency and more memory use. At this time, a worker keeps its history and gets only new events.

The numbers

The preview function WorkflowsFastPath is off when you install the new version. With the function on, median step latency fell from 553 to 153 milliseconds in benchmarks by Diagrid. Less data is for workers made with the Java and Python kits only.

What is not known

Diagrid gave no test results for the removal of the Placement part. It tells only that users do not install a stateful system. All sidecars must use 1.19 before the new mode starts.

Insight: Agent tools are free, and the aim is the layer

Dapr is open source, Webcmd is free, and Vercel Labs released agent-desktop as open source. Diagrid also has a dashboard to control the Dapr version change. This reads as a move to control the layer that agents operate on. The source does not tell which Diagrid item has a price. Look for the item that comes after each free tool.
