    Description

      sequencefiles are invaluable for storing compressed/binary data. but when we use them to store serialized records - we don't use the key part at all (just put something dummy there to satisfy the api). i have heard of other projects using the same tactics (jaql/cascading).

      so this is a request to have a modified version of sequencefiles that don't incur the space and compute overhead of processing/storing these dummy keys.
