1. One or more computer-storage media having computer-executable instructions embodied thereon that, when executed, perform a method of processing and partitioning tenant geospatial data, the method comprising: receiving from at least one tenant a set of geospatial data comprising an updated version of an already-existing geospatial data set stored in association with both processor memory and file system memory of a multi-tenant geospatial data index; processing the set of geo spatial data into a format optimized for storage in the processor memory; partitioning the set of geospatial data into a processor memory portion and a file system memory portion; storing both the processor memory portion and the file system memory portion in association with a shared file storage system; and initiating a staged upload of both the processor memory portion and the file system memory portion to the processor memory and the file system memory of the multi-tenant geospatial data index.
