• Configure TTL for a specific item

Prerequisites:

Before starting this module, you should have experience of building cloud applications with Microsoft C# or a similar programming language.

Quiz 1: Knowledge check

Q1. What parameter[s] are required to read an item in Azure Cosmos DB SQL API?

• Both an ID and partition key value
• Only an ID
• Only a partition key value

Q2. Which method should you use to update an item in Azure Cosmos DB SQL API using the .NET SDK?

• PatchItemAsync<>
• UpdateItemAsync<>
• UpsertItemAsync<>

Q3. Which class contains the methods for Create, Read, Update, and Delete point operations on items in Azure Cosmos DB SQL API?

• Database
• Container
• CosmosClient

Module 2: Perform cross-document transactional operations with the Azure Cosmos DB SQL API

Perform operations on multiple items in single logical units of work.

Learning objectives:

After completing this module, you’ll be able to:

• Create a transactional batch and review results
• Implement optimistic concurrency control for an operation

Prerequisites:

Before starting this module, you should have experience of building cloud applications with Microsoft C# or a similar programming language.

Quiz 1: Knowledge check

Q1. What method parameters are required to create a transaction batch using container.CreateTransactionBatch()?

• Partition Key
• Partition Key, List of Operations
• None

Q2. You are using the ItemRequestOptions class to configure a request to enable optimistic concurrency control. Which header should you use to check for an exact value of an _etag?

• SessionToken
• IfNoneMatchEtag
• IfMatchETag

Q3. Which property of the TransactionalBatchResponse returns the HTTP status code indicating success or failure of the transaction?

• ErrorMessage
• StatusCode
• IsSuccessStatusCode

Module 3: Process bulk data in Azure Cosmos DB SQL API

Perform bulk operations on Azure Cosmos DB in bulk from code using the SDK.

Learning objectives:

After completing this module, you’ll be able to:

• Use C# task asynchronous programming model and “bulk” support in the Azure Cosmos DB SQL API .NET SDK

Prerequisites:

Before starting this module, you should have experience of building cloud applications with Microsoft C# or a similar programming language.

Quiz 1: Knowledge check

Q1. Which property of the CosmosClientOptions class enables the ability to run multiple operations concurrently and transparently at scale?

• AllowBulkExecution
• ConnectionMode
• LimitToEndpoint

Q2. Which one of these statements is considered a best practice when working with the bulk features of the SDK?

• Stream APIs are not compatible with the bulk features of the SDK.
• Assume that bulk will save you on actual throughput costs versus individual operations.
• Configure the partition key for each operation configured in a set of tasks.
