google-big-queryHow do I use Google Big Query to zip files?

Google BigQuery does not natively support zipping files. To use BigQuery to zip files, you will need to export the files to Google Cloud Storage, then use the gsutil command line tool to zip the files.

The following example code will export the file named my_file.csv from BigQuery to Google Cloud Storage, then zip the file:

bq extract --destination_format=CSV 'my-project:my-dataset.my_table' gs://my-bucket/my_file.csv
gsutil cp gs://my-bucket/my_file.csv gs://my-bucket/my_file.zip

This code will create a zip file named my_file.zip in the Google Cloud Storage bucket my-bucket.

The code consists of two parts:

1. bq extract: This command will export the table my-project:my-dataset.my_table from BigQuery to the file my_file.csv in the Google Cloud Storage bucket my-bucket.
2. gsutil cp: This command will copy the file my_file.csv from the Google Cloud Storage bucket my-bucket to the file my_file.zip in the same bucket.
