Fields
name

string

The resource name of the reservation, e.g., projects/*/locations/*/reservations/team1-prod. The reservationId must only contain lower case alphanumeric characters or dashes. It must start with a letter and must not end with a dash. Its maximum length is 64 characters.

slotCapacity

string (int64 format)

Baseline slots available to this reservation. A slot is a unit of computational power in BigQuery, and serves as the unit of parallelism.

Queries using this reservation might use more slots during runtime if ignoreIdleSlots is set to false, or autoscaling is enabled.

If edition is EDITION_UNSPECIFIED and total slotCapacity of the reservation and its siblings exceeds the total slotCount of all capacity commitments, the request will fail with google.rpc.Code.RESOURCE_EXHAUSTED.

If edition is any value but EDITION_UNSPECIFIED, then the above requirement is not needed. The total slotCapacity of the reservation and its siblings may exceed the total slotCount of capacity commitments. In that case, the exceeding slots will be charged with the autoscale SKU. You can increase the number of baseline slots in a reservation every few minutes. If you want to decrease your baseline slots, you are limited to once an hour if you have recently changed your baseline slot capacity and your baseline slots exceed your committed slots. Otherwise, you can decrease your baseline slots every few minutes.

ignoreIdleSlots

boolean

If false, any query or pipeline job using this reservation will use idle slots from other reservations within the same admin project. If true, a query or pipeline job using this reservation will execute with the slot capacity specified in the slotCapacity field at most.

autoscale

object (Autoscale)

The configuration parameters for the auto scaling feature.

concurrency

string (int64 format)

Job concurrency target which sets a soft upper bound on the number of jobs that can run concurrently in this reservation. This is a soft target due to asynchronous nature of the system and various optimizations for small queries. Default value is 0 which means that concurrency target will be automatically computed by the system. NOTE: this field is exposed as target job concurrency in the Information Schema, DDL and BQ CLI.
