Hello, I have a question about checkpointing. If I want to disable checkpointing in flink-sql-client, how can I achieve this? I’ve tried several approaches, but after a few attempts it feels like checkpointing cannot be fully disabled at all. Flink version 2.2.1

Flink SQL> SET 'execution.checkpointing.interval' = 0;

That's correct, https://nightlies.apache.org/flink/flink-docs-master/docs/dev/table/config/ doesn't list checkpointing as a configuration option there

it turns out i had to disable checkpointing globally on the cluster level by removing

execution.checkpointing.interval: 1min

from

config.yaml

flink config
