In many applications, it’s important to make sure your code handles creating any resources that it needs in order to run. Otherwise, you’ll have to manually create those resources whenever you want to run your application with a new AWS account. For example, if you have an application that needs to store data in an […]

Today we’re excited to talk about a brand new open source project on our GitHub page for managing Apache Tomcat sessions in Amazon DynamoDB! DynamoDB’s fast and predictable performance characteristics make it a great match for handling session data. Plus, since it’s a fully-managed NoSQL database service, you avoid all the work of maintaining and […]

No matter what type of application you’re developing, it’s a safe bet that it probably needs to save or load data from a central data store, such as Amazon S3. During development, you can take advantage of the Amazon S3 management tools provided by the AWS Toolkit for Eclipse, all without ever leaving your IDE. […]

Earlier this year, Amazon DynamoDB released support for local secondary indexes.

S3Object contains an S3ObjectInputStream that lets you stream down your data over the HTTP connection from Amazon S3. Since the HTTP connection is open and waiting, it’s important […]

Today we have another guest post from a member of the Amazon DynamoDB team, Pejus Das. The Amazon DynamoDB service provides fast and predictable performance with seamless scalability. It also has a list of common errors that can occur during request processing. You probably have a set of test suites that you run before you […]

If you aren’t able to drop […]
