I think the main difference between our flavor of SQL and CockroachDB's (or PostgreSQL's) is that we don't have a specific "json" data type, but rather:

1. We don't need you to specify the types of any fields, indeed, we don't even need to know upfront which top-level fields ("columns") may exist in the document.

2. You don't need to use special operators / functions to deal with JSON-typed values.
