1. A computer-implemented method for federated query processing comprising:

  • receiving one or more source queries associated with a data set;

    storing the one or more source queries as one or more historical queries;

    determining one or more column constant pairs associated with the one or more historical queries;

    based on the one or more column constant pairs, determining a partitioning column constant pair;

    determining a first subset of the one or more column constant pairs that has a first pre-defined relation to the partitioning column constant pair;

    determining a second subset of the one or more column constant pairs that has a second pre-defined relation to the partitioning column constant pair;

    based on the partitioning column constant pair, partitioning the data set into a first subset of the data set and a second subset of the data set;

    receiving a source query;

    determining a source column constant pair associated with the source query;

    comparing the source column constant pair to the partitioning column constant pair; and

    based on the comparing, generating a result of the source query from at least one of the following;

    a view, the first subset of the data set, and the second subset of the data set.
