Evaluating encoding history for late encoding binding of data

Abstract:

Late encoding binding can be applied to data added to a data set according to the encoding history for the data set. When a request to add data is received, an evaluation of the encoding history can determine whether a currently specified encoding for the data can be changed. If changeable, a different encoding scheme for the data may be identified and the data added to the data set according to the different encoding scheme.
