Flat File Sources

Flat File Sources

A mapping that is running in a Hadoop environment can read a flat file source from a native environment.
Consider the following limitations when you configure the mapping to read a flat file source:
  • You cannot use an indirect source type.
  • The row size in a flat file source cannot exceed 190 MB.
  • You cannot use a command to generate or to transform flat file data and send the output to the flat file reader at run time.
