Abstract
In an embodiment, a database platform receives query instructions for a query on a database, where the query instructions include instructions for a geospatial-function join that includes a geospatial-function predicate. The database platform generates a query-execution plan based on the query instructions, including replacing the geospatial-function join with one or more interval joins that each include one or more predicates implied by the geospatial-function predicate. The database platform inserts, into the query-execution plan above the one or more interval joins, a filter operator that applies the geospatial-function predicate. The database platform obtains results of the query at least in part by executing the query-execution plan, and returns the query results in response to the query.
