I am now using the S3 StreamingFileSink to send data to an S3 bucket.
If/when the network connection has issues, it seems to put Flink into an
irrecoverable state. Am I understanding this correctly? Any suggestions on
how to troubleshoot / fix?
Here is what I'm observing:
*1. Network is dropped *
*2. S3 connections do not exit gracefully*
