### Search before asking - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar. ### Fluss version main (development) ### Please describe the bug 🐞 LogScanner's consumption latency keeps increasing during cluster upgrades. It appears the upgrade caused a Netty worker to hang. Fluss currently defaults to only 1 Netty worker thread (`netty.client.num-network-threads`=1), resulting in network channel congestion. The issue disappears when increasing `netty.client.num-network-threads` to 3. ### Solution _No response_ ### Are you willing to submit a PR? - [x] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
