-------------------------------------
Summary: Schema Change: Screen Operator should filter behaviors
unsupported by particular clients
Key: DRILL-4018
URL: https://issues.apache.org/jira/browse/DRILL-4018
Project: Apache Drill
Issue Type: Improvement
Components: Execution - Relational Operators
Reporter: Jacques Nadeau
Assignee: amit hadke
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.
