Setup and Requirements

Qwiklabs setup

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).

Note: Use an Incognito or private browser window to run this lab. This prevents any conflicts between your personal account and the Student account, which may cause extra charges incurred to your personal account.

• Time to complete the lab---remember, once you start, you cannot pause a lab.

Note: If you already have your own personal Google Cloud account or project, do not use it for this lab to avoid extra charges to your account.

Cloud Console

How to start your lab and sign in to the Google Cloud console

1. 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

2. 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.

Cloud Shell is a virtual machine that is loaded with development tools. It offers a persistent 5GB home directory and runs on the Google Cloud. Cloud Shell provides command-line access to your Google Cloud resources.

1. Click Activate Cloud Shell at the top of the Google Cloud console.

When you are connected, you are already authenticated, and the project is set to your Project_ID, . The output contains a line that declares the Project_ID for this session:

Your Cloud Platform project in this session is set to {{{project_0.project_id | "PROJECT_ID"}}}

gcloud is the command-line tool for Google Cloud. It comes pre-installed on Cloud Shell and supports tab-completion.

2. (Optional) You can list the active account name with this command:

gcloud auth list

3. Click Authorize.

Output:

ACTIVE: * ACCOUNT: {{{user_0.username | "ACCOUNT"}}} To set the active account, run: $ gcloud config set account `ACCOUNT`

4. (Optional) You can list the project ID with this command:

gcloud config list project

Output:

[core] project = {{{project_0.project_id | "PROJECT_ID"}}} Note: For full documentation of gcloud, in Google Cloud, refer to the gcloud CLI overview guide.

Task 1. Create a Cloud Spanner instance

1. Your first task is to create an instance.

2. You may complete this step using the Cloud Console or the gcloud CLI.

3. Your instance must have following attributes:

Item	Value
Name	banking-ops-instance
Region
Allocate Compute Capacity	Unit - Nodes // Quantity - 1

An example gcloud CLI command to create an instance is as follows:

gcloud spanner instances create my-sample-instance \ --config=regional-{{{primary_project.default_region|Region}}} \ --description="Sample Instance" \ --nodes=1

4. Click Check my progress to verify the objective.

3. Your database must have following attribute:

Item	Value
Name	banking-ops-db

An example gcloud CLI command to create a database is as follows:

gcloud spanner databases create my-sample-db \ --instance=my-sample-instance

4. Click Check my progress to verify the objective.

Create a database

Task 3. Create tables in your database

1. Your database must have a total of four (4) tables - Portfolio, Category, Product, and Customer.

2. The tables must be defined as listed below.

An example DDL command to create a table is as follows:

CREATE TABLE Sample ( SampleId INT64 NOT NULL, SampleName STRING(MAX) ) PRIMARY KEY (SampleId);

Table: Portfolio

Primary Key: PortfolioId

Column	Datatype
PortfolioId	INT64 NOT NULL
Name	STRING(MAX)
ShortName	STRING(MAX)
PortfolioInfo	STRING(MAX)

Table: Category

Primary Key: CategoryId

Column	Datatype
CategoryId	INT64 NOT NULL
PortfolioId	INT64 NOT NULL
CategoryName	STRING(MAX)
PortfolioInfo	STRING(MAX)

Table: Product

Primary Key: ProductId

Column	Datatype
ProductId	INT64 NOT NULL
CategoryId	INT64 NOT NULL
PortfolioId	INT64 NOT NULL
ProductName	STRING(MAX)
ProductAssetCode	STRING(25)
ProductClass	STRING(25)

Table: Customer

Primary Key: CustomerId

Column	Datatype
CustomerId	STRING(36) NOT NULL
Name	STRING(MAX) NOT NULL
Location	STRING(MAX) NOT NULL

Task 4. Load simple datasets into tables

1. Three of your tables, Portfolio, Category, and Product, will be loaded with simple, low-volume datasets.

2. You may employ any method to load these tables.

Note: The data elements provided are ordered to match the order of the columns of the corresponding table.

An example DML command to load a single row into a table is as follows:

INSERT INTO Sample (SampleId, SampleName) VALUES (1, "Banking");

Table: Portfolio

1, "Banking", "Bnkg", "All Banking Business" 2, "Asset Growth", "AsstGrwth", "All Asset Focused Products" 3, "Insurance", "Insurance", "All Insurance Focused Products"

Table: Category

1,1,"Cash" 2,2,"Investments - Short Return" 3,2,"Annuities" 4,3,"Life Insurance"

Table: Product

1,1,1,"Checking Account","ChkAcct","Banking LOB" 2,2,2,"Mutual Fund Consumer Goods","MFundCG","Investment LOB" 3,3,2,"Annuity Early Retirement","AnnuFixed","Investment LOB" 4,4,3,"Term Life Insurance","TermLife","Insurance LOB" 5,1,1,"Savings Account","SavAcct","Banking LOB" 6,1,1,"Personal Loan","PersLn","Banking LOB" 7,1,1,"Auto Loan","AutLn","Banking LOB" 8,4,3,"Permanent Life Insurance","PermLife","Insurance LOB" 9,2,2,"US Savings Bonds","USSavBond","Investment LOB"

3. Click each Check my progress to verify the objectives.

Create and Load Tables

Task 5. Load a complex dataset

1. You will load the Customer table with a much larger set of data.

2. A file named Customer_List_500.csv contains 500 rows of data and is located in the following public Cloud Storage bucket. You may reference or download it as necessary.

gsutil URI

gs://cloud-training/OCBL375/Customer_List_500.csv

HTTP URL

https://storage.googleapis.com/cloud-training/OCBL375/Customer_List_500.csv

3. You may recall from the lab Cloud Spanner - Loading Data and Performing Backups that a few options exist to load larger datasets. These include using Dataflow or a client library in Batch mode. You may choose to create simple insert statements. The decision is yours but you must load all 500 rows.

4. Utilize any method that you prefer to load the 500 row datafile. Some methods will require edits to the datafile which will require downloading it to your local machine. Please be sure to make a backup file if you choose that option.

5. Note: if you use Dataflow should ensure that you specify the Regional Endpoint and reset the Dataflow API via the following gcloud command:

gcloud services disable dataflow.googleapis.com --force gcloud services enable dataflow.googleapis.com

6. Also if you use a Dataflow template you will be required to provide a Mainfest file named manifest.json. Below is a sample manifest.json that you can use to guide creation of a file appropriate for loading the Customer table.

Note: This sample cannot be used as is, you must update it accordingly.

Note:

{ "tables": [ { "table_name": "TABLE_NAME", "file_patterns": [ "gs://BUCKET/FOLDER/FILENAME.SUFFIX" ], "columns": [ {"column_name" : "UPDATE_COLUMN1", "type_name" : "UPDATE_DATATYPE" }, {"column_name" : "UPDATE_COLUMN2", "type_name" : "UPDATE_DATATYPE" }, {"column_name" : "UPDATE_COLUMN3", "type_name" : "UPDATE_DATATYPE" } ] } ] }

7. Click Check my progress to verify the objective.

Load Customer table

Task 6. Add a new column to an existing table

1. As part of your DBA responsibilities you are required to add a new column called MarketingBudget to the Category table.

2. The column MarketingBudget must have a datatype of INT64.

3. Adding a new column is accomplished by a DDL command. You may issue the DDL via a gcloud command, the Cloud Console, or client library call.

An example gcloud CLI command to add a column to a table is as follows:

gcloud spanner databases ddl update my-sample-db \ --instance=my-sample-instance \ --ddl='ALTER TABLE Sample ADD COLUMN SampleValue INT64;'

4. Click Check my progress to verify the objective.
