Working on #4908, I needed a way to emit multiple events (specifically: extract multiple logs from one AWS CloudTrail log object).
This implementation works by adding a
emit_multipleflag to theremaptransform, which expects the result of a VRL program to be an array when set. The objects of the array are then emitted as individual events.The current implementation wouldn't be useful yet without having a
mapfunction on VRL arrays to parse the individual CloudTrail logs from the parent object.Unfortunately, I did not discover #6330, #6031 and #7038 before working on this, so I'll put this PR back as draft and maybe it can serve as an example in this discussion.
