Feature

April 16, 2026

Feature

You can stream messages from Pub/Sub directly to a Bigtable table using Bigtable subscriptions. This feature lets you write streaming messages to Bigtable without needing a separate subscriber such as Dataflow. This feature is available in Preview.

April 06, 2026

Feature

Pub/Sub now offers the AI Inference Single Method Transform (SMT). This SMT lets you get inferences on Pub/Sub messages from Vertex AI models. The model's inferences are added to each message, making them available for downstream processing along with the original message data.

The change is being rolled out in a phased manner over the rest of the week. For more information, see AI Inference SMT. This feature is generally available.

March 13, 2026

Feature

You can now use the Pub/Sub remote MCP server to manage Pub/Sub resources. You can create, list, get, update, and delete Pub/Sub topics, subscriptions, and snapshots, as well as publish messages to topics.

This feature is in Preview.

January 20, 2026

Feature

Pub/Sub is now available in the Bangkok region (asia-southeast3). For more information, see Cloud locations.

General availability: Pub/Sub now offers Single Message Transforms (SMTs) that enable lightweight modifications to message data and attributes directly within Pub/Sub. SMTs can be set as properties of topics or subscriptions. The change is being rolled out in a phased manner over the rest of the week. For more information about SMTs, see Single Message Transforms (SMTs) overview.
