events_partitioned is partitioned by event_date, which is the UTC date of event_ts. The engine can only skip partitions when the query filters on event_date directly; a filter on event_ts alone reads every partition.
Return the events with event_ts from 2024-03-05 22:00:00 (inclusive) up to 2024-03-06 02:00:00 (exclusive).
Your WHERE clause must include a comparison on event_date itself (and must not wrap event_date in a function or cast) so that only the needed partitions are read; the grader checks both.
Columns: event_id, event_ts, user_id, event_type. Sort by event_ts, then event_id.
