Description

In some situations, a client may not be able to accommodate schema changes. We need to update the Screen operator to have configurable behavior according to what a client supports. One example is schema change. While Drill supports schema changes, many clients can't deal with these. We need to come with a set of schema change criteria that map to coercion, warning or error and then implement that filtering within the screen operator.
