Google BigQuery
Google BigQuery is a fully managed, serverless data warehouse on Google Cloud that enables interactive SQL analysis of datasets ranging from gigabytes to petabytes. It uses a columnar storage format optimized for analytical (OLAP) workloads and separates storage from compute so both scale independently without any infrastructure management. Users can interact with it through the Google Cloud Console, the bq command-line tool, or client libraries in Python, Java, Go, and other languages.
In 2026, AI teams depend on BigQuery as the central hub for storing, querying, and preparing the large-scale training and evaluation datasets that feed ML pipelines. BigQuery ML lets data engineers and scientists train classification, regression, and time-series models directly in SQL without moving data to a separate platform, which collapses the gap between data engineering and applied ML. Demand for BigQuery skills is consistently high across roles in data engineering, analytics engineering, and applied AI, making it one of the most sought-after cloud data skills in the market.
