Properties
Autoscale
public Reservation.Types.Autoscale Autoscale { get; set; }The configuration parameters for the auto scaling feature. Note this is an alpha feature.

Concurrency
public long Concurrency { get; set; }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.

CreationTime
public Timestamp CreationTime { get; set; }Output only. Creation time of the reservation.

Edition
public Edition Edition { get; set; }Edition of the reservation.

IgnoreIdleSlots
public bool IgnoreIdleSlots { get; set; }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 slot_capacity field at most.
| Property Value | |
|---|---|
| Type | Description |
bool | |
MultiRegionAuxiliary
public bool MultiRegionAuxiliary { get; set; }Applicable only for reservations located within one of the BigQuery multi-regions (US or EU).
If set to true, this reservation is placed in the organization's secondary region which is designated for disaster recovery purposes. If false, this reservation is placed in the organization's default region.
NOTE: this is a preview feature. Project must be allow-listed in order to set this field.
| Property Value | |
|---|---|
| Type | Description |

Name
public string Name { get; set; }The resource name of the reservation, e.g.,
projects/*/locations/*/reservations/team1-prod.
The reservation_id 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.

ReservationName
public ReservationName ReservationName { get; set; }ReservationName-typed view over the Name resource name property.
| Property Value | |

SlotCapacity
public long SlotCapacity { get; set; }Minimum 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 ignore_idle_slots is set to false.
If total slot_capacity of the reservation and its siblings
exceeds the total slot_count of all capacity commitments, the request will
fail with google.rpc.Code.RESOURCE_EXHAUSTED.
NOTE: for reservations in US or EU multi-regions, slot capacity constraints are checked separately for default and auxiliary regions. See multi_region_auxiliary flag for more details.
