Accessing the Event store

Google maintains documentation on how to access and use Google BigQuery.

We urge you to download the Google Cloud SDK, which contains several tools that you’ll need to connect to BigQuery from the command line. Connecting from the command line is often a good place to start testing and interacting with BigQuery. In particular, we urge you to install the gcloud and bq command-line tools.

Unizin member access

Unizin is required to seek authorization from your Institution’s UDP Data steward. Unizin will not grant any individual access to the Event store without explicit authorization from a recognized UDP data steward.

Request access to the UDP event store at your institution.

When your institutional UDP data steward has approved access, you will use a Google Service account provided by the Unizin Services team (note: multiple service accounts can be created for a diverse set of data needs at your institution).

When you’ve installed the Google Cloud SDK, the first thing you should do is configure your local system to use a Google Service Account. Your Google Service Account was created by Unizin Services. The Unizin Services team provides you with a key to the Google Service account. The key is a JSON file that you need to store in a secure place on your local system. Once the Google Service Account key is in your local system, authenticate it against the UDP:

Authenticate with GCP

gcloud auth activate-service-account --key-file=<path-to-JSON-keyfile>

You should now have access to query your UDP Event store.

To query your Event store, you can use the bq command-line tool:

Authenticate with GCP

bq query “SELECT COUNT(id) ROM WHERE event_time > '2021-01-01'

Of course, this is just the tip of the iceberg. Once you’ve validated the above basic forms of access, you will likely want to explore your data in a more programmatic way. The following references may help provide you with the means of using the Event store in your applications and services:
