Throttle — Controls the rate at which messages are passed to the next node in the route
The Throttle pattern controls the flow of messages from one step in the route to the next.
The Throttle pattern can appear anywhere in the body of a route.
Table 45 describes the properties you can specify using the properties editor.
Table 45. Throttle Properties
| Name | Description |
|---|---|
| Language | Specifies the language to use to process the expression. |
| Async Delayed | Specifies whether processing tasks will be scheduled for processing at a later
time. The default is Disabled. |
| Caller Runs When Rejected | Specifies whether tasks rejected by the thread pool are executed by the calling
thread. The default is Disabled. |
| Description | Specifies a text description for the node. This description is included in the generated XML file, but it is informational only. It is not used by Apache Camel. |
| Executor Service Ref | Specifies a reference for looking up the
executorService to use for
thread pool management. |
| Id | Specifies a unique identifier for the endpoint. The tooling automatically generates an id for a node when it is created, but you can remove that id or replace it with your own. The Camel debugger requires all nodes with a breakpoint set to have a unique id. You can use the id to refer to endpoints in your Camel XML file. |
| Reject Execution | Specifies whether the throttler throws a
ThrottlerRejectExecutionException
when the request rate exceeds the limit. |
| Time Period Millis | Specifies the time period, in milliseconds, used by the throttler. The default is
1000 milliseconds. |
