Hi folks,
I’m working on migrating from v0.12 to 0.13 and I noticed that when I fetched a batch in 0.12 I could include a `query` in the `batch_kwargs` to, say, cast strings to numeric as a preprocessing step. This was super helpful as we have some postgres tables that need a bit of TLC before they’re ready for validation. Is there an analogue with `BatchRequest` in v0.13? Did this functionality migrate elsewhere during the refactor?

This capability was not included in the initial version of the new API in 0.13. We have revisited this since and will release an update that will allow to create a Validator from a SQL query, using RuntimeDataConnector. Please watch for release anncouncements.
