BigQuery is Google Cloud's serverless, fully managed data warehouse for large-scale analytics. It ranks around #11 in real-world database usage (roughly 6.5% share) and is a favorite for companies that need to run massive SQL queries across billions of rows without managing any servers โ you just write SQL and Google handles the infrastructure.
BigQuery uses Standard SQL, with a few extensions for working with nested and semi-structured data. A typical analytical query aggregates over a huge public or internal dataset:
SELECT
country,
COUNT(*) AS total_orders,
SUM(order_amount) AS revenue
FROM
`my_project.sales.orders`
WHERE
order_date BETWEEN '2026-01-01' AND '2026-06-30'
GROUP BY
country
ORDER BY
revenue DESC
LIMIT 10; -- scans only the columns/partitions it needs, billed by bytes scanned
BigQuery is accessed through the Google Cloud Console, the bq command-line tool, or client libraries โ there's nothing to install or provision.
# install the Google Cloud CLI, then authenticate
gcloud auth login
# run a query directly from the terminal
bq query --use_legacy_sql=false 'SELECT COUNT(*) FROM `bigquery-public-data.samples.shakespeare`'
