How to arrive in sequence with a time interval at the source?

Hello, I would like to configure a source to create flow items of different types and quantities, as shown in image 1,

however the arrival rate of these items must follow a probability function, and in batch, as shown in image 2. It is Is it possible to do this configuration somehow?

Hello @Leohgs7,

The arrival sequence option will allow you to instantly create those items of those quantities and Types. Are you wanting the items to arrive in that quantity but at intervals and batched? For instance, 50 of Type 5 will be created and arrive in batches/groups of 3 in 1 second intervals. Is each Type a different interval and batch quantity? Do the types arrive dependent or independent of the other types? For example, Does Type 1 need to finish arriving before Type 2 starts or do all the Types start their arrival regardless of the other Types.

Question 1: yes, exactly as you described.

Question 2: Each type of product has different batches and intervals, and they are dependent, type 2 only starts when all type 1s have been processed.

Hello @Leohgs7,

You can accomplish this with a Scheduled source and combiner. I have created a global table that have the batch quantity and process time. One thing to note with the combiner is the first item that enters is considered the container object and is not counted towards the batch quantity, so If you wanted to batch by 3 then the value in the combiner would be 2.
