Description

What did you do?
  • Create a Kafka changefeed
  • Keep writing data until the Kafka reported some transient errors ("broken pipe" etc) (?)
What did you expect to see?
  • Automatic retry allowed the message to be written.
What did you see instead?
  • The sink is stuck not confirming success or failure, and thus CheckpointTS is stuck.

v8.5.7
