摘要
Disclosed herein are system, method, and computer program product embodiments for providing a spatio-temporal index for high-update workloads and query processing. An embodiment operates by a first thread retrieving an update record from a first queue, the update record comprising a location component and a temporal component indicating a location of one of a plurality of mobile devices at a specified time, and updating a columnar-store database with the update record. The embodiment further operates by a second thread identifying a spatial grid of a spatial temporal index within a memory corresponding to the location component of the update record, and updating a temporal index of the spatial grid based on the temporal component of the update record.
