A lot of this code is similar to the RawSqsMessageHandler. We should not duplicate this code.
I think the best option is to update the existing RawSqsMessageHandler to support an injectable message strategy.
It might look like:
interface MessageFieldStrategy {
List<Event> parseEvents(String messageBody);
}
This has some advantages of being able to use buffer.writeAll for the whole batch and the attribute code is shared for all.

I removed the BulkMessageHandler and added strategies instead. buffer.writeAll is also used instead of buffer.write now

A lot of this processing can be shared, which has the added benefit of avoiding extra memory. You can do this in the refactoring that I suggest above.
That is, before the loop over the List<Event>, create a Map<String, String> for all the attributes. Then re-use those values. This should reduce both compute and memory.

great idea, the metadata/attributes of a bulk message would remain the same for every event in that message
