Thx @Jose Gonzalez​ , this makes sense..

What I do not fully understand is the role of the Delta table transaction log in this matter.

E.g. maxFilesPerTrigger is set to 100 files for each micro-batch.

If the Delta transactions of the streaming source looks somewhat like this:E.g. there are 70 files per transaction. Will the micro batch 1 contain files from version 0 and 1, micro batch 2 contain files from version 1 and 2, and so on? So the Delta Table version is not really relevant for the streaming micro badge sizing?
