Complex File Sources on Azure Data Lake Storage Gen2

Complex File Sources on Azure Data Lake Storage Gen2

You can use a PowerExchange for HDFS or a PowerExchange for Microsoft Azure Data Lake Storage Gen2 connection to read data from Azure Data Lake Storage Gen2 data objects.
The PowerExchange for Microsoft Azure Data Lake Storage Gen2 connection is an Azure Blob File System (ABFS) connection. You can use it if you have a PowerExchange for Microsoft Azure Data Lake Storage Gen2 connection license.
The following table shows the complex files that a PowerExchange for Microsoft Azure Data Lake Storage Gen2 mapping can process within Azure Data Lake Storage Gen2 in the Hadoop environment:
