BigQuery Basics

BigQuery is a serverless, AI-ready data platform that enables high-speed analysis of large datasets using SQL and Python. Its disaggregated architecture separates compute and storage, allowing them to scale independently while providing built-in machine learning, geospatial analysis, and business intelligence capabilities.

Setup and Basic Usage

1. Enable the BigQuery API:

   bashCopy

   gcloud services enable bigquery.googleapis.com
   

2. Create a Dataset:

   bashCopy

   bq mk --dataset --location=US my_dataset
   

3. Create a Table:

   Create a file named schema.json with your table schema:

   jsonCopy

   [
     {
       "name": "name",
       "type": "STRING",
       "mode": "REQUIRED"
     },
     {
       "name": "post_abbr",
       "type": "STRING",
       "mode": "NULLABLE"
     }
   ]
   

   Then create the table with the bq tool:

   bashCopy

   bq mk --table my_dataset.mytable schema.json
   

4. Run a Query:

   bashCopy

   bq query --use_legacy_sql=false \
   'SELECT name FROM `bigquery-public-data.usa_names.usa_1910_2013` \
   WHERE state = "TX" LIMIT 10'
