1. On Flink 1.10 when I look at the topology overview, the AsyncFunctions show non-zero values for Bytes Received; Records Received; Bytes Sent but Records Sent is always 0... yet the next step in the topology shows approx the same Bytes Received as the async sent (modulo minor delays) and a non-zero Records Received. Is the “Records Sent of an AsyncFunction is always displayed as zero” a bug?
2. Is there an Async Sink? Or do I just rewrite my Sink as an AsyncFunction followed by a dummy sink? What’s the recommendation if the sink performing blocking I/O is proven to be the root cause of back pressure? Thanks in advance for your help -- Sent from my phone
