> Segment has a 'key' member that holds accounting information to the reader's
> current key buffer, position, and length. There is a 384 byte overhead per
> segment since the account is done with the DataInputBuffer class which
> derives from DataInputStream which has underlying byte[80] and char[80] among
> significant pieces. This jira aims to reduce the overhead per segment
