minute

Generic Description

Extracts the minute component from a temporal value. It is documented separately because time construction, sequence ordering, window parameters, and as-of behavior materially change analytical meaning.

Simple example:

RETURN minute()

Consumer-Level Explanation

Use it for minute-grain analysis. Prefer this function when the temporal assumption should be visible to the planner, especially for event streams, freshness checks, and sequence features.

More Detailed Explanation

minute belongs to the temporal construction, conversion, or extraction surface. Use it to make time semantics explicit in the query text: whether a value is date-only, time-only, timestamp-like, duration-like, current-time dependent, or bucketed to a chosen calendar unit.

Advanced Example

This example names the event stream and operational context before applying minute, which helps planner tooling preserve the intended sequence semantics.

MATCH (u:User)-[e:VIEWED]->(d:Document)
TIME e.ts BETWEEN datetime('2025-01-01T00:00:00Z') AND datetime('2025-02-01T00:00:00Z')
WITH u, e, d,
     unpivot(properties(d.metadata)) AS metadata_rows,
     date_trunc('day', e.ts) AS day_bucket,
     minute(e.ts) AS focused_value
RETURN u.user_id, d.title, day_bucket, metadata_rows, focused_value
LIMIT 10
