Abstract: The disclosed technology is generally directed to graph queries with reduced latencies. In one example of the technology, there is a cross-tenancy collaboration between two different tenancies: a first tenancy that is homed in a first geographical region and a second tenancy that is homed in a second geographical region. In the first geographical region, a first set of graph data is stored. The first set of the graph data is associated with the first tenancy. A portion of the first set of the graph data to be copied from the first geographical region to the second geographical region is determined. In response to determining the portion of the first set of the graph data, a copy of the portion of the first set of the graph data is stored in the second geographical region.
