Resource: Reservation
A reservation is a mechanism used to guarantee slots to users.

Fields | |
---|---|
name |
The resource name of the reservation, e.g., |
slot |
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 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. |
ignore |
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 |
The configuration parameters for the auto scaling feature. |
concurrency |
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 BigQuery CLI. |
creation |
Output only. Creation time of the reservation. A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: |
update |
Output only. Last update time of the reservation. A timestamp in RFC3339 UTC "Zulu" format, with nanosecond resolution and up to nine fractional digits. Examples: |
edition |
Edition of the reservation. |
primary |
Output only. The current location of the reservation's primary replica. This field is only set for reservations using the managed disaster recovery feature. |
secondary |
Optional. The current location of the reservation's secondary replica. This field is only set for reservations using the managed disaster recovery feature. Users can set this in create reservation calls to create a failover reservation or in update reservation calls to convert a non-failover reservation to a failover reservation(or vice versa). |
original |
Output only. The location where the reservation was originally created. This is set only during the failover reservation's creation. All billing charges for the failover reservation will be applied to this location. |
Autoscale
Auto scaling settings.
JSON representation |
---|
{ "currentSlots": string, "maxSlots": string } |
Fields | |
---|---|
current |
Output only. The slot capacity added to this reservation when autoscale happens. Will be between [0, maxSlots]. Note: after users reduce maxSlots, it may take a while before it can be propagated, so currentSlots may stay in the original value and could be larger than maxSlots for that brief period (less than one minute) |
max |
Number of slots to be scaled when needed. |
