限定符和类型	方法和说明
`Rowtime`	`timestampsFromExtractor(TimestampExtractor extractor)` 已过时。 Sets a custom timestamp extractor to be used for the rowtime attribute.
`Rowtime`	`timestampsFromField(String fieldName)` 已过时。 Sets a built-in timestamp extractor that converts an existing `Long` or `Types.SQL_TIMESTAMP` field into the rowtime attribute.
`Rowtime`	`timestampsFromSource()` 已过时。 Sets a built-in timestamp extractor that converts the assigned timestamps from a DataStream API record into the rowtime attribute and thus preserves the assigned timestamps from the source.
`Map<String,String>`	`toProperties()` 已过时。 Converts this descriptor into a set of properties.
`Rowtime`	`watermarksFromSource()` 已过时。 Sets a built-in watermark strategy which indicates the watermarks should be preserved from the underlying DataStream API and thus preserves the assigned watermarks from the source.
`Rowtime`	`watermarksFromStrategy(WatermarkStrategy strategy)` 已过时。 Sets a custom watermark strategy to be used for the rowtime attribute.
`Rowtime`	`watermarksPeriodicAscending()` 已过时。 Sets a built-in watermark strategy for ascending rowtime attributes.
`Rowtime`	`watermarksPeriodicBounded(long delay)` 已过时。 Sets a built-in watermark strategy for rowtime attributes which are out-of-order by a bounded time interval.
