Optimize a Cassandra query
Optimize a Cassandra query

    * 'get_istorage_attrs' was always queried to get the metadata
    information about the base of a numpy object, but in reality this
    call is redundant as the first query is unneccesary because the data
    is already there. It is only needed in the case where the base_numpy
    has some value meaning that the this numpy is a view of a previous
    one and therefore you should get the original numpy acting as
    'base'.
