A data input sub-system of a parallelized database system includes processing core resources operable to obtain divisions of data slabs of a dataset and compress the divisions of data slabs using a null elimination compression scheme to produce divisions of compressed data slabs, A first data slab of a first division of data slabs of the divisions of data slabs is compressed using the null elimination compression scheme to produce a first compressed data slab. The first compressed data slab includes first compressed data and first compression information. The processing core resources are further operable to store a respective division of compressed data slabs of the divisions of compressed data slabs.
