Datastore: Qwik Start

Overview
In this lab, you learn how to store and query data in Datastore using the Google Cloud console.
Setup and requirements
Before you click the Start Lab button
Read these instructions. Labs are timed and you cannot pause them. The timer, which starts when you click Start Lab, shows how long Google Cloud resources will be made available to you.
This hands-on lab lets you do the lab activities yourself in a real cloud environment, not in a simulation or demo environment. It does so by giving you new, temporary credentials that you use to sign in and access Google Cloud for the duration of the lab.
To complete this lab, you need:
- Access to a standard internet browser (Chrome browser recommended).
- Time to complete the lab---remember, once you start, you cannot pause a lab.
How to start your lab and sign in to the Google Cloud console
-
Click the Start Lab button. If you need to pay for the lab, a pop-up opens for you to select your payment method. On the left is the Lab Details panel with the following:
- The Open Google Cloud console button
- Time remaining
- The temporary credentials that you must use for this lab
- Other information, if needed, to step through this lab
-
Click Open Google Cloud console (or right-click and select Open Link in Incognito Window if you are running the Chrome browser).
The lab spins up resources, and then opens another tab that shows the Sign in page.
Tip: Arrange the tabs in separate windows, side-by-side.
Note: If you see the Choose an account dialog, click Use Another Account. -
If necessary, copy the Username below and paste it into the Sign in dialog.
{{{user_0.username | "Username"}}} You can also find the Username in the Lab Details panel.
-
Click Next.
-
Copy the Password below and paste it into the Welcome dialog.
{{{user_0.password | "Password"}}} You can also find the Password in the Lab Details panel.
-
Click Next.
Important: You must use the credentials the lab provides you. Do not use your Google Cloud account credentials. Note: Using your own Google Cloud account for this lab may incur extra charges. -
Click through the subsequent pages:
- Accept the terms and conditions.
- Do not add recovery options or two-factor authentication (because this is a temporary account).
- Do not sign up for free trials.
After a few moments, the Google Cloud console opens in this tab.

Test completed task
Click Check my progress to verify your performed task. If you have completed the task successfully you will granted with an assessment score.
Task 2. Run a query
Cloud Datastore supports querying data by kind or by Google Query Language (GQL); the instructions below walk you through the steps of doing both.
Run kind queries
- Click Query by kind.
- Select
Task
as the kind.
The query results show the Task entity that you created.
- Next, add a query filter to restrict the results to entities that meet specific criteria:
- Click ADD TO QUERY dropdown.
- In the dropdown lists, select
WHERE
, done, == (Equal to), Boolean and false. - Click Run.
- The results show the
Task
entity that you created, since itsdone
value isfalse
.
- Now try a query of
WHERE
, done, == (Equal to), Boolean and true. The results do not include theTask
entity that you created, because itsdone
value is nottrue
.
Run GQL queries
- Click the Query by GQL tab.
- In the query box add the following:
Task
is case sensitive.- Click Run query.
The query results show the Task entity that you created.
- Now add a query filter to restrict the results to entities that meet specific criteria.
Run this query:
Task
and done
are case sensitive.The results show the Task entity that you created, since its done
value is false
.
- Now run this query:
The results do not include the Task
entity that you created, because its done
value is not true
.
Task 3. Test your understanding
Below are multiple-choice questions to reinforce your understanding of this lab's concepts. Answer them to the best of your abilities.
