ADLS Gen2 supports multiple data formats for writing data including Avro, Delimited, ORC, and XML. However, there are some limitations to using certain formats with ADLS Gen2 destination.
Avro is a data serialization system that supports rich data structures and dynamic schema evolution. ADLS Gen2 supports writing data in Avro format, so Option A is not correct.
Delimited data formats like CSV (comma-separated values) and TSV (tab-separated values) are also supported by ADLS Gen2 destination. Therefore, Option B is not correct.
ORC (Optimized Row Columnar) is another columnar storage format that is optimized for Hadoop workloads. ADLS Gen2 destination supports ORC format, so Option C is not correct.
XML is a markup language that is widely used for data exchange. However, ADLS Gen2 does not support writing data in XML format. Therefore, Option D is correct.
To summarize, the correct answer is Option D. ADLS Gen2 destination does not support writing data in XML format. All the other options (A, B, C) are incorrect since ADLS Gen2 supports writing data in Avro, Delimited, and ORC formats.
