Construct a record iterator. The underlying iterator is optimized for
short iterations.  If it determined that the iterator is to be used 
for a large number of iterations, the underlying iterator is switched
to one optimized for longer iterations.
@param minKey minimum allowed primary key.
@param maxKey maximum allowed primary key.
@param startKey the first primary key value.
@throws IOException thrown if IO error occurs
