Depending on how the key value pair is encoded, you could use the
TypeInformationKeyValueSerializationSchema where you provide the
BasicTypeInfo.STRING_TYPE_INFO and
PrimitiveArrayTypeInfo.BYTE_PRIMITIVE_ARRAY_TYPE_INFO as the key and value
type information. But this only works if your data was serialized in a
similar fashion.
