# google-cloud-bigquery-reservation — Google Cloud Bigquery Reservation API client library

License: permissive · Maintenance: active · Downloads: 147.5K/mo

## What it is and what it does

This is Google's official Python client library for the BigQuery Reservation API, a service that lets you manage reserved compute capacity on Google Cloud. It wraps the underlying gRPC and REST APIs into a Pythonic interface, handling authentication, serialization, and error handling automatically. The library is built on google-api-core and uses proto-plus for message handling, making it consistent with other Google Cloud client libraries.

You use it to programmatically create, modify, and query BigQuery reservations—the dedicated compute slots that give you predictable query performance and costs. It's primarily for infrastructure-as-code workflows, automation, and integration with larger cloud management systems. The library requires Python 3.10 or later and assumes you have Google Cloud credentials configured; it's production-stable and actively maintained by Google.

Use it for:

- Automate BigQuery reservation provisioning and scaling in response to workload demands or cost optimization policies.
- Query and monitor existing reservations and slot commitments as part of a cloud cost management dashboard.
- Integrate BigQuery capacity management into infrastructure-as-code pipelines (Terraform, Pulumi, etc.).
- Build internal tools to manage team or project-level reservation allocations across multiple Google Cloud projects.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Python client library for managing BigQuery reservations on Google Cloud Platform, enabling programmatic control over reservation capacity and allocation.

Yes, if you need to manage BigQuery reservations programmatically. The library is production-stable, actively maintained, has no known vulnerabilities, and low install friction. It's the official Google client, so it's the right choice for reservation automation. Not needed if you only query BigQuery data or manage reservations exclusively through the console.

## Install

pip install google-cloud-bigquery-reservation
uv add google-cloud-bigquery-reservation
poetry add google-cloud-bigquery-reservation

## Installing google-cloud-bigquery-reservation

Before you install: Low install friction with a pure-wheel distribution. Actively maintained as of 2026-06-03 with recent activity. Depends on standard Google Cloud libraries (google-api-core, google-auth, grpcio, proto-plus, protobuf, grpc-google-iam-v1), all widely used and stable.

License in practice: Apache-2.0 permissive license allows commercial and private use with minimal restrictions; suitable for most production environments.

Quickstart:

pip install google-cloud-bigquery-reservation

from google.cloud import bigquery_reservation_v1

client = bigquery_reservation_v1.ReservationServiceClient()
project = "projects/my-project"
reservations = client.list_reservations(parent=project)

Requires Python >= 3.10. Google Cloud credentials must be configured (via GOOGLE_APPLICATION_CREDENTIALS or Application Default Credentials).

Verify before relying:

- Specific reservation management operations supported (create, update, delete, list) beyond what the excerpt confirms.
- Whether the library handles slot commitments and flex slots or only standard reservations.
- Real-world performance characteristics and latency for large-scale reservation queries.
