user: I am using apache camel 2.18.0 version. I am using seda queue with concurrent consumers option. What I am looking for is a way to control how long a message can remain in the queue itself. For ex: Say a timeout configuration is set for 2 min, and once the message reached the queue, if it stays for more than 2 min, exception should be thrown. In seda documentation this timeout property is available for ex: from("direct:start").to("seda:queue?timeout=120000"); // 2 minutes (in milliseconds) But this means message should reach the queue in 2min. So, if there is no such property to cause timeout on message age in a queue, is it true that Messages can stay in the queue until they are dequeued for processing? If I want to control how long messages can stay in the queue, I may need to implement custom logic in application to periodically check and remove messages from the queue if they exceed a certain age?

assistant: The seda component in Apache Camel does not provide a built-in configuration option to control the maximum time a message can stay in the queue (message age) before being dequeued.

If you want to control how long messages can stay in the queue and implement a timeout on the message age, you would need to implement custom logic in the application to periodically check and remove messages from the queue if they exceed a certain age.

To achieve this, you can implement a custom background process that periodically checks the messages in the queue and removes the ones that have exceeded the specified age limit.

Here's a high-level approach to implementing this custom logic:

1. Create a background process or a scheduled task that runs at regular intervals.
2. Inside this process or task, iterate through the messages in the queue and check their age.
3. Remove the messages that have exceeded the specified age limit.

You can use the ScheduledExecutorService in Java to implement this background task.

If you want more control over the behavior, you can consider using a different message broker that provides features for managing message expiration and time-to-live (TTL) settings for messages in the queue.

Unfortunately, with the Apache Camel 2.18.0 version, the seda component does not have built-in support for message age timeout, so custom logic or using a different message broker may be necessary to achieve the desired behavior.
