Filter by data type

Hi,

Is it possible to create a filter based on field data type?

I want to create a downsampling task, whereby I move all data older than a month to a low-res bucket. However, I don’t need to downsample event / discrete data. Effectively, only fields that are not boolean or string will be aggregated. For this, I was thinking of writing a query that selects all data that is not boolean or string… The closest I could think of was using regular expressions, but that doesn’t offer to compare data types I think, just complex patterns. I could look for strings like “false” or “true”… but that seems only like a solution for booleans.

Thoughts?
