> Push the {{WatermarkStrategy}} into TableSourceScan in the interface {{SupportsWatermarkPushDown}}. Sometimes users define watermark on computed column. Therefore, we will push the computed column of rowtime into {{WatermarkStrategy}} first. For more info, please take a look at [discussion|http://apache-flink-mailing-list-archive.1008284.n3.nabble.com/Merge-SupportsComputedColumnPushDown-and-SupportsWatermarkPushDown-td44387.html].
