1. A method comprising:

  • storing a plurality of datasets;

    loading a first dataset of the plurality of datasets into a first cache unit and a second cache unit of a plurality of cache units;

    determining, by a processing device, that a hit ratio is below a first hit ratio threshold associated with the first cache unit and above a second hit ratio threshold associated with the second cache unit, wherein the first hit ratio threshold is different from the second hit ratio threshold; and

    responsive to determining that the hit ratio is below the first hit ratio threshold associated with the first cache unit and above the second hit ratio threshold associated with the second cache unit, loading a second dataset of the plurality of datasets into the first cache unit, wherein the first dataset of the plurality of datasets is different than the second dataset of the plurality of datasets.
