Batching at the second node about ciw HOT 2 OPEN

Dear @lec00q

You are correct, and this is the expected behaviour. In Ciw, "batching" only applies to external arrivals. Arrivals from another node are not batched.

I am note sure immediately how to model the behaviour you want. It may be possible to use Ciw's custom node feature: https://ciw.readthedocs.io/en/latest/Guides/behaviour.html to overwrite the node's release methods (line 394 in https://github.com/CiwPython/Ciw/blob/master/ciw/node.py), so that if there are less than three individuals reasy to be released it passes, but once there are 3 individuals waiting to be released then all three are released simultaneously.

I hope that helps somewhat.

Dear @geraintpalmer,

thank you for your suggestion and sorry for the delayed answer. I have managed to obtain the behaviour described by inheriting from the custom node, as you said.

However, it came out a bit complicated and I had to modify quite a lot of methods: begin_service_if_possible_change_shift, begin_service_if_possible_accept, begin_service_if_possible_release, detatch_server. Not sure if I have made something wrong and if it could have been easier (probably!) but if you need some hints on how I did let me know. I think that for many real cases this can be a very nice add-on functionality.

Thanks!
