Lets Talk CDC Change Feed Playground
Hacktoberfest 2025 Submission
Plan · Practice · Share

Prototype change data capture without leaving the browser.

Create a lightweight schema, act on rows, and watch the resulting change feed update in real time.

Explore real-world scenarios

Load curated CDC blueprints to jumpstart your experiments.

Quick start

Take the guided path to your first change feed in under a minute.

Step 1 Pending

Model your schema

Define columns and mark at least one primary key.

Step 2 Pending

Populate rows

Seed realistic data or insert rows manually.

Step 3 Pending

Stream events

Trigger operations and watch the change feed update live.

Step 1

Model your schema

Add columns, choose types, and mark primary keys so downstream operations know how to locate rows.

Operate

Edit row values

Provide values for your columns, then choose an operation to emit events.

Schema walkthrough

Add and drop a column to see how capture methods react during the stream.

Step 2

Populate the table

Review current rows, seed realistic data, or clear the table to reset.

Step 3

Inspect change events

Filter operations, include before-images, and export NDJSON to share scenarios.
