IPC Classification
CPC Classification
A data input sub-system of a parallelized database system includes processing core resources. Data blocks of a first memory device of a first processing core resource correspond to a first set of logical data block addresses. The processing core resources are operable to obtain divisions of data slabs, compress the divisions of data slabs, and store a respective division of compressed data slabs. A first data slab of a first division of data slabs is mapped to at least a portion of the first set of logical data block addresses that includes at least a portion of a first set of fixed size data fields. The first data slab is compressed to produce a first compressed data slab and the first compressed data slab is mapped to a reduced amount of fixed size data fields of the 10 at least the portion of the first set of fixed size data fields.
