Why dremio no decimal type, In practice, we need the exact value with decimals.
This is on our roadmap and we will report back once it becomes available.
Where is the roadmap? I can see.
At this time we do not publish a roadmap for Dremio.
@chenguohui, With 3.3 we are supporting decimals with Parquet and ORC. Can you give it a try and let us know if it solves your use cases?
