Ok, then I think the actual cause for the well-formed documents to be missing 
also isn't because the {{BulkProcessor}} is dropping them due to the malformed 
documents, but simply because at-least-once isn't properly supported in the ES 
connector yet (see FLINK-5487). Any documents that were buffered in the 
{{BulkProcessor}} at the time of failure simply could not be recovered.

With the suggested {{FailedActionRequestHandler}}, you can simply just drop the 
malformed document or re-process it if you want to.
