Would you like chDB print a progress bar on console or notebook?
Or, you need a async way to query and a getProgress function?

This, clearly. Having an async query API would allow to get progress but maybe also profile event, which would be awesome.

Thank you, that's a good suggestion.
And it's possible after chdb 2.3 release which move most heavy lifting works out of query function.
