Name | Default | Description |
---|---|---|
size | 1000 | The maximum size of the SEDA queue |
concurrentConsumers | 1 | Camel 1.6.1/2.0: Number of concurrent threads processing exchanges. |
waitForTaskToComplete | Camel 2.0: Option to specify if the caller should wait for the async task to be complete or not before continuing. The following 3 options is supported: Always, Newer or IfReplyExpected. The first two options is self explained. The last will only wait if the message is Request Reply based. The default option is IfReplyExpected. See more information about Async messaging. |
