Record Header Attributes
The MapR FS origin creates record header attributes that include information about the originating file for the record.
You can use the record:attribute
or
record:attributeOrDefault
functions to access the information
in the attributes. For more information about working with record header attributes,
see Working with Header Attributes.
The MapR FS origin creates the following record header
attributes:
- file - Provides the file path and file name where the record originated.
- offset - Provides the file offset in bytes. The file offset is the location in the file where the record originated.
