Unique task queue task names only for active duration

Question

I want to guarantee that a task is not in a task queue more then once, so I generate a unique name based on it's payload. But, that task name is reserved for up to 7 days, which is not what I want; I only want it reserved for the duration the task is queued; it could be immediately re-queued.

Once a Task with name N is written, any subsequent attempts to insert a Task named N will fail. Eventually (at least seven days after the task successfully executes), the task will be deleted and the name N can be reused.

Is there a way to check if the named task is already in the queue then add it if it's not? Or a totally different approach?

Answer 1

You need to take a different approach - for example, including the time interval over which you want the name to be unique in the task name, or including a 'job number' that you increment for each new task.
