This week, we are running a series of five daily blog posts that will explain new DynamoDB changes and how they relate to the AWS SDK for .NET. This is the fourth blog post, and today we will be discussing the Object Persistence Model. Object Persistence Model The Object Persistence Model API provides a simple […]

This week, we are running a series of five daily blog posts that will explain new DynamoDB changes and how they relate to the AWS SDK for .NET. This is the third blog post, and today we will be discussing conversion schemas. Conversion Schemas Document doc = new Document(); doc[“Id”] = 1; doc[“Product”] = “DataWriter”; […]

Last week, Amazon DynamoDB added support for JSON document data structures. With this update, DynamoDB now supports nested data in the form of lists (L type) and maps (M type). Also part of this update was native support for booleans (BOOL type) and nulls (NULL type). This week, we will be running a series of […]

When using the AWS SDK for .NET, you may find yourself wondering how to use various components of the SDK and, more importantly, how to properly dispose of resources once you are done with them. This blog post reviews the lifecycles of various SDK objects and the best practices for using them. Lifecycles There are […]

The release of AWS SDK for .NET version 2.1.0 has introduced a number of changes to the high-level Amazon DynamoDB classes. Now, less markup is required to use classes with DynamoDBContext, as the SDK now infers reasonable default behavior. You can customize this behavior through app.config/web.config files and during run time through the SDK. In […]

Amazon Simple Storage Service (S3) provides a simple method to control the lifecycle of your S3 objects. In this post, we examine how you can easily set up rules to delete or archive old data in S3 using the AWS SDK for .NET. Lifecycle Rules Lifecycle configurations are associated with a bucket. A lifecycle configuration […]

Amazon DynamoDB is a fast NoSQL database service offered by AWS. DynamoDB can be invoked from .NET applications by using the AWS SDK for .NET. The SDK provides three different models for communicating with DynamoDB. This blog post is the first of a series that describes the various APIs, their respective tradeoffs, best practices, and […]

A few months ago we added a helper utility to the SDK called EC2Metadata. This is a class that provides convenient access to EC2 Instance Metada. The utility surfaces most instance data as static strings and some complex data as .NET structures. For instance, the following code sample illustrates how you can retrieve the current […]

Earlier this week, you may have noticed that the assembly AWS.Extensions—which contained DynamoDBSessionStateStore—has been renamed to AWS.SessionProvider. Our original intent with AWS.Extensions was to create a place for SDK extensions, which aren’t strictly part of the AWS SDK for .NET. We have since developed another extension, DynamoDBTraceListener, a TraceListener that allows the logging of trace […]

We recently introduced the DynamoDBTraceListener, a System.Diagnostics TraceListener that can be used to log events straight to Amazon DynamoDB. In this post, we show how simple it is to configure the listener and how to customize the data that is being logged. Configuration You can configure the listener either through code or by using a […]
