Complex File Sources on ADLS

Complex File Sources on ADLS

You can use a PowerExchange for HDFS or a PowerExchange for Microsoft Azure Data Lake Store connection to read data from ADLS data objects. If you use a PowerExchange for Microsoft Azure Data Lake Store connection, you cannot read compressed binary files from ADLS.
The following table shows the complex files that a PowerExchange for Microsoft Azure Data Lake Store connection can process within ADLS storage in the Hadoop environment:
File Type
Supported Formats
Supported Engines
Avro
  • Flat
  • Hierarchical
    1
Spark
JSON
  • Flat
  • Hierarchical
    1
Spark
Parquet

To run on the Spark engine, the complex file read operation must be enabled to project columns as complex data type.
