  • one or more processors;

    a cluster manager, implemented on the one or more processors;

    an index;

    a first database cluster containing one or more database nodes including a first database node, the first database cluster configured to operate according to a first database protocol; and

    a data set distributed amongst the one or more database nodes of the first database cluster;

    wherein the first database node reports a first data range within the first database cluster;

    wherein the index contains a second data range associated with the first database node, the second data range different from the first data range;

    wherein, responsive to a received request having a target data value from a requesting process, the cluster manager performs a query of the index in response to the request, and communicably directs the requesting process to access the first database cluster based on a determination that the target data value falls within the second data range.
