A database system is operable to determine a dataset for storage that includes, for each row, a plurality of column values corresponding to a plurality of columns. A plurality of column slab data are generated from the dataset, where each of the plurality of column slab data includes column values for one of the plurality of columns. Each of a plurality of compression dictionaries are trained from a corresponding one of the plurality of column slab data. Each segment of the plurality of segments is generated based on writing a set of compressed column slabs to the each segment based on compressing each of a corresponding set of the plurality of column slab data as a set of variable-length compression frames written to the each segment based on applying a corresponding one of the plurality of compression dictionaries.
