# Redis

### Overview

The Redis trigger enable event-based flow execution. When a Redis client sends an event to a topic monitored by the Redis trigger for a flow, the flow begins executing. 

Like [REST](https://cxfabric.gitbook.io/docs/developer-tools/components/triggers/rest), [Webook](https://cxfabric.gitbook.io/docs/developer-tools/components/triggers/web-hook), and [socket.io](https://cxfabric.gitbook.io/docs/developer-tools/components/triggers/socket-io) triggers, a Redis trigger is associated with an automatically generated endpoint URL that the Redis client connects to before sending events to Redis topics that the Redis trigger defines.
