Search before asking

• I searched in the issues and found nothing similar.

Read release policy

• I understand that unsupported versions don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker.

Version

Linux, JDK 17

Broker: 3.0.5
Client: image: streamnative/pulsar-io-jdbc-clickhouse:4.0.1.3

Minimal reproduce step

Currently not known how to reproduce.

What did you expect to see?

All messages from the non-persistent partioned topics are sinked into a clickhouse database.

What did you see instead?

After some time of a working sink (hours to days), presumably after a network error, the consumer reconnects to the broker and no further messages are processed.

(no more stats are logged)

The sink is then in a WAITING state:

and the metrics for sinked messages drop of a cliff:
