Wanted to touch base to see what the status was of DRILL-1257. We've run into a few instances where JSON/Mongo data is changing types and Drill is unable to query it (e.g. a numeric type becomes a string type).
I know this is a pretty massive change with a lot of tough decisions to make on how to handle that, but wanted to see what the roadmap looked like - that is, is it in the near future? At the moment I'm trying to work out some sort of temporary fix (i.e.. "upgrading" vectors, e.g. converting a float vector to varchar vector in my above example). As we're allowing users to run aggregations etc. against their data without having knowledge of the schema, we can't really use "all_text_mode" and do our own casting (apart from the huge performance degradation associated with it).
