Abstract
Techniques are disclosed relating to performing a join operation with bitmap indexes of virtual data sources (VDSs). A distributed compute cluster having a set of compute nodes may maintain a plurality of VDSs based on a set of corresponding origins. A given VDS of the plurality of VDSs may include a bitmap index representative of a portion of data stored at the set of origins. The distributed compute cluster may receive a request for data stored across at least first and second bitmap indexes of the plurality of VDSs. The distributed compute cluster may perform a join operation to generate a join result having data from the first and second bitmap indexes. The distributed compute cluster may return a response that includes the join result.
