## Name

Threads — Specifies that all steps after this node are processed asynchronously

## Usage

The Threads pattern specifies that the nodes after it in the route are processed asynchronously. This means that the route can use multiple threads to process messages and that the client will not wait for a reply.

The Threads pattern can be used anywhere in the body of a route.

## Properties

Table 103 describes the properties you can specify using the properties editor.
