Problem

This issue is related to the newly supported ArrowStream format of ClickHouse #24074. I found that the sink did not support the Int128 type when I tried to use the arrow_stream format and got this error.

I'll see if I can add this one after the PR for complex types is merged -- had to do some heavy refactoring so it'll be much easier once that's done
