  • Method Details

    • timestampsFromField

      public Rowtime timestampsFromField(String fieldName)
      Deprecated.
      Sets a built-in timestamp extractor that converts an existing Long or Types.SQL_TIMESTAMP field into the rowtime attribute.
      Parameters:
      fieldName - The field to convert into a rowtime attribute.

    • timestampsFromSource

      public Rowtime timestampsFromSource()
      Deprecated.
      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.

      Note: This extractor only works in streaming environments.

    • timestampsFromExtractor

      public Rowtime timestampsFromExtractor(TimestampExtractor extractor)
      Deprecated.
      Sets a custom timestamp extractor to be used for the rowtime attribute.
      Parameters:
      extractor - The TimestampExtractor to extract the rowtime attribute from the physical type.

    • watermarksPeriodicAscending

      public Rowtime watermarksPeriodicAscending()
      Deprecated.
      Sets a built-in watermark strategy for ascending rowtime attributes.

      Emits a watermark of the maximum observed timestamp so far minus 1. Rows that have a timestamp equal to the max timestamp are not late.

    • watermarksPeriodicBounded

      public Rowtime watermarksPeriodicBounded(long delay)
      Deprecated.
      Sets a built-in watermark strategy for rowtime attributes which are out-of-order by a bounded time interval.

      Emits watermarks which are the maximum observed timestamp minus the specified delay.

      Parameters:
      delay - delay in milliseconds

    • watermarksFromSource

      public Rowtime watermarksFromSource()
      Deprecated.
      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.

    • watermarksFromStrategy

      public Rowtime watermarksFromStrategy(WatermarkStrategy strategy)
      Deprecated.
      Sets a custom watermark strategy to be used for the rowtime attribute.

    • toProperties

      public Map<String,String> toProperties()
      Deprecated.
      Converts this descriptor into a set of properties.
      Specified by:
      toProperties in interface Descriptor
