> Key: FLINK-25363
> URL: https://issues.apache.org/jira/browse/FLINK-25363
> Project: Flink
> Issue Type: Sub-task
> Components: API / Python, Table SQL / Planner
> Reporter: Timo Walther
> Assignee: Francesco Guardiani
> Priority: Major
> Labels: pull-request-available

> The following classes are legacy from the old Table API.
> {code}
> import org.apache.flink.table.planner.expressions.PlannerNamedWindowProperty;
> import org.apache.flink.table.planner.expressions.PlannerProctimeAttribute;
> import org.apache.flink.table.planner.expressions.PlannerRowtimeAttribute;
> import org.apache.flink.table.planner.expressions.PlannerWindowEnd;
> import org.apache.flink.table.planner.expressions.PlannerWindowProperty;
> import org.apache.flink.table.planner.expressions.PlannerWindowStart;
> import org.apache.flink.table.planner.plan.logical.LogicalWindow;
> import org.apache.flink.table.planner.plan.logical.SessionGroupWindow;
> import org.apache.flink.table.planner.plan.logical.SlidingGroupWindow;
> import org.apache.flink.table.planner.plan.logical.TumblingGroupWindow;
> {code}
> However, currently they are used in {{ExecNode}} and partially are serialized
> into the JSON plan. Also Python depends on it. Instead we should introduce a
> small POJO structure with enums. E.g. {{WindowSpec}} with {{WindowProperty}}
> enum or so. It can be located in the runtime module if Python needs this
> information during runtime.
