> Currently {{Table}} and {{TableWrite}} in Flink Table Store have a fixed schema. However to consume schema changes, Flink Table Store CDC sinks should have the ability to change its schema during a streaming job.
> This require us to pause and store the states of a {{TableWrite}}, then create a {{TableWrite}} with newer schema and recover the states in the new {{TableWrite}}.
