----------------------------------

             Summary: Rename table.optimizer.union-all-as-breakpoint-disabled to table.optimizer.union-all-as-breakpoint.enabled
                 Key: FLINK-20322
                 URL: https://issues.apache.org/jira/browse/FLINK-20322
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / API
    Affects Versions: 1.12.0
            Reporter: godfrey he
             Fix For: 1.12.0


{{table.optimizer.union-all-as-breakpoint-disabled}} is defined in {{RelNodeBlockPlanBuilder}}  and is an internal experimental config. While {{disabled}} and {{false}} as default value is very obscure.  I suggest to change {{table.optimizer.union-all-as-breakpoint-disabled}} to {{table.optimizer.union-all-as-breakpoint-enabled}} and use {{true}} as default value, which is easier to understand. As this config is an internal experimental config, we don't mark it as deprecated.
