------------------------------------
Assignee: Caizhi Weng
> Introduce LeafPredicate interface and children method in Predicate
> ------------------------------------------------------------------
>
> Key: FLINK-27835
> URL: https://issues.apache.org/jira/browse/FLINK-27835
> Project: Flink
> Issue Type: Sub-task
> Components: Table Store
> Affects Versions: table-store-0.2.0
> Reporter: Caizhi Weng
> Assignee: Caizhi Weng
> Priority: Major
> Labels: pull-request-available
>
> We'd like to expose a more simple interface in the row data abstraction
> layer. Instead of the {{withPartitionFilter}}, {{withKeyFIlter}} and
> {{withValueFilter}} methods in {{FileStoreScan}}, we'd like to introduce
> {{RowDataScan}} containing only one {{withFilter}} method. We'll enclose the
> logic to extract partition predicate or key predicate in this method.
> To extract partition predicate from a big predicate object we'll need to look
> into this predicate tree. That's why we'll need {{children}} method and
> {{LeafPredicate}} interface to help us represent this tree structure.
