How do I stop SSIS package creating empty flat file at the destination?

SSIS will create an empty flat file, even if unchecked: “column names in a first data row”. The workarounds are: remove such file by a file system task if @RowCountWriteOff = 0 just after the execution of a dataflow.

What is the difference between a flat file source and a raw file source?

csv) are one of the most popular data sources used, Raw Files are designed to deliver higher performance when transferring data. SSIS Flat Files require parsing and validation, while the data in Raw Files are stored in native format and requires no translation and little parsing.

What is HDFS file destination in SSIS?

The HDFS File Destination component enables an SSIS package to write data to a HDFS file. The supported file formats are Text, Avro, and ORC. To configure the HDFS File Destination, drag and drop the HDFS File Source on the data flow designer and double-click the component to open the editor.

What is raw file source in SSIS?
