}Query BigQuery reservation timeline
One row per reservation and time bucket, carrying reserved and consumed slot capacity alongside concurrency signals for the reservation pool.
Returns one row per combination of the requested dimensions, carrying the requested measures. Each row is keyed by dimension and measure name. row_count is the number of rows in items: results are not paginated, so an aggregation with more rows than limit is cut short at limit rather than continued under a page_token. Send X-Team-Id to evaluate the query as a team you belong to; rows are then limited to what that team’s roles reach.
Use this route to see how a BigQuery reservation’s slots were configured and used over time, and how long jobs waited to start. A reservation is a pool of slots that jobs run on. Its baseline is always on. Autoscale adds slots on demand. Idle baseline can be lent to, or borrowed from, other reservations in the same commitment scope. The route has no cost measures: for capacity cost, use bigquery-commitment-scope-days. For job cost by reservation, use bigquery-workloads. The *_slot_s measures are slot-seconds (divide by 3,600 for slot-hours). baseline_slots, max_slots and the *_slot_hours_per_hour measures are slot counts: the average number of slots over the hours observed, the same at every grain. Naming hour reads the hourly table. All other requests read the daily table.

}Authorizations
Organization API key (sl_…).
Headers
Act as this team: rows are limited to what the team's roles reach instead of the caller's own. The caller must be a member of the team or hold the organization-wide permission the route requires.
The organization ID the request is scoped to.
Body
Aggregate BigQuery reservation capacity and consumption over time.
Daily and hourly reservation timelines answer this model. A request that
names hour reads the hourly rollup; everything else reads the daily one,
which is also the only grain carrying observed_hours and
autoscale_active_hours.
Aggregates to compute over the matching rows.

Columns to group the aggregates by. Each is returned on every row.

Maximum rows to return. Omit for no limit. An aggregation that produces more rows than this is silently cut short at the limit.
x >= 1Return the SQL that produced the rows alongside them, for inspecting how a result was computed. Not every query endpoint publishes its SQL; where it does not, the field stays null.
Reshape the result so the named dimensions become columns rather than rows. Each remaining dimension yields one row, carrying a pivot_data object keyed by the pivoted dimension values. Every name in pivot.on must also appear in dimensions.

Show child attributes
Return the result as a tree rather than a flat list, grouping the named dimensions into one level per tree depth. One request fetches the top level; a follow-up naming rollup.parent_paths fetches the children of the nodes expanded so far, so a deep hierarchy is read a level at a time. Every name in rollup.dimensions must also appear in dimensions.
Show child attributes
Show child attributes
Aggregate the matching rows. Set false to return the underlying rows as they are, projecting the requested dimensions with no grouping — a listing rather than an aggregation. It is honored only for a request that asks for no measures and no measure_filters, since an aggregate has to group to be computable; limit, when set, bounds the rows returned either way.
Response
Successful Response
Opaque cursor for the next page; empty/absent on the last page.
Best-effort total for the filtered result set; may be null when expensive.
The SQL that produced these rows, returned only when the request asks for it. Database and schema names are left as placeholders. Null when the request did not ask for it, or when this endpoint does not publish its SQL.
