Many browsers have a maximum number of simultaneous HTTP connections they will make. If one API request takes a long time to complete, it can block other requests from starting. In a hospital setting where Wifi and cellular connectivity can be slow, reducing the number of HTTP requests will speed up your application and improve the overall experience for your users.

Bundle need to be committed together, you can set
If the operations can happen in parallel and one failure does not mean the other operations should fail, you can set
