A system, technique, or computer program product generates a simplified version of a geometry, based on a target number of points to be included in the output. A first plurality of points, representative of a geometry, is received. The simplified version of the geometry is generated by, at least, expanding a segment of a simplified version of the geometry. The segment is identified for expanding by determining that a point associated with the segment is at a distance from the segment that exceeds a tolerance value, and is includable in the simplified version of the geometry without causing the simplified version of the geometry to exceed the target size.

Dynamic plan interpretation may be implemented to perform queries. A query is received at a database system. A plan to perform the query is generated. For at least a portion of the plan to perform the query, a domain-specific language may be applied to interpret and execute the portion of the plan to perform the query using one or more previously compiled executors instead of generating and compiling code to execute the portion of the plan. Returning a result of the query according to the execution of the plan.
