Abstract
Disclosed herein are systems and methods for point-based relation splitting in geospatial-function-implied interval joins. In an embodiment, a data platform receives a query that applies a geospatial-function predicate to first and second geography data objects from first and second relations. The second relation is divided into point and non-point subsets based on the second data geography object. The data platform routes the point subset along a first path that includes a one-sided interval join that applies, to the first relation and the point subset, an interval-join predicate implied by the geospatial-function predicate. The data platform routes the non-point subset along a second path that does not include the one-sided interval join. The data platform obtains query results at least in part with a filter that applies the geospatial-function predicate to outputs of the one-sided interval join and the second path, and outputs the query results.
