    o

    Object that contains message ksb.csle.common.proto.StreamDidentProto.IdenPartialReductionInfo IdenPartialReductionInfo contains attributes as follows:

    • method: not used currently.
    • generalizedColumnInfo: the configuration about the generalization step
    • columnHandlePolicy: consider the given columns all together, or individually.
    • fieldInfo: the info about column attributes (identifier, sensitive, ..)
    • check: the method how to verify the performance of anonymized data
