Anyone have any good tricks for upgrading a sequence file.
We maintain a sequence file like a flat file DB and the primary object in
there changed in recent development.
It's trivial to write a job to read in the sequence file, update the object,
and write it back out in the new format.
But since sequence files read and write the key/value class I would either
need to rename the model object with a version number, or change the header
of each sequence file.
Just wondering if there are any nice tricks to this.
