Thanks for you guidance Robert!
Do you think disabling watermarking would help in terms of a slight
performance boost in such scenarios?

Hi Bob,
if you don't need any time characteristics, go with processing time.
Ingestion time will call System.currentTimeMillis() on every incoming
record, which is an somewhat expensive call.
Event time (and ingestion time) will attach a long field to each record,
making the records 8 bytes larger
