Bad event clubbed together with good events in bad s3 bucket

[alex]

This has been discussed recently, in this thread:

POSTed bad events, are they all dropped?

Looking to reprocess some bad events, and we are sending in batches of 50 from the collectors through a POST. When there is 1 bad event in the batch, is the whole batch dropped? I can see in the bad events the line includes them all, invalid or not, but just not sure if the ones that were good were actually passed on or not. Cheers
