Writing hierarchical data in an elastic mapping

Writing hierarchical data in an
elastic mapping

You can use a Target transformation in an
elastic mapping
to write hierarchical data to complex files, such as Avro, JSON, and Parquet files.
Consider the following guidelines when you write hierarchical data:
  • You must use an Amazon S3 V2 or Azure Data Lake Storage Gen2 connection to write hierarchical data. For more information, see the help for the appropriate connector.
  • You must create a new target at run time.
  • Do not use a parameter for the target connection or the target object.
