BigQuery Storage API example

In 2021, Google released a new API for streaming data into BigQuery tables. It is referred to variously as the "Storage API" and the "Write API". This repository provides an example of how to use this API from Golang to stream rows into a bigquery table.

First install the Google Cloud command line tools and authenticate with

gcloud auth application-default login

Next create a bigquery dataset and a table. In this example our table will contain two columns: a name and an age:

# create the dataset
bq mk mydataset

# create the table
bq --project_id=myproject mk -t mydataset.mytable name:string,age:integer

Next we stream data into the table. You may need to edit the "project" constant at the top of the main source file in this repository.

go run *.go

The data that was streaming into the table is a constant at the top of the main source file. You can now view it with:

$ bq query 'select * from mydataset.mytable'
