Aaron Kimball commented on HADOOP-6708:
---------------------------------------
In working on Sqoop, I need to import records which may be several gigabytes in
size each. I require a file format that allows me to store these records in an
efficient, grouped fashion.
Users may then want to open a file containing many such records and
partially-read individual records, but still access subsequent records
efficiently.
I'm attaching to this issue a proposal for a _LobFile_ format which will store
these large objects. (The basis for this work surrounds import of BLOB and
CLOB-typed columns.) The specification proposal analyzes available file formats
and my understanding of why they aren't appropriate here.
