Amazon spits out offline DynamoDB tester

Even disconnected devs can now crank the Dynamo

Designing a Defense for Mobile Applications

Amazon has released a tool to let developers test apps that use the DynamoDB API, and to do so offline.

The DynamoDB Local test tool was announced by Amazon on Thursday, and gives devs access to a client-side database that supports the complete DynamoDB API, but doesn't manipulate any tables or data in DynamoDB itself."

The technology is available as an executable Java archive file, and can run on Windows, Mac, and Linux systems. It is compatible with version 7 of the Java Runtime Environment.

DynamoDB Local will plonk a local database into the JAR directory, and devs then configure their apps to use the local endpoint – DynamoDB listens on port 8000. The tech does not have service-level agreements for durability or availability. "It is not recommended for production use," Amazon states – a funny comment, given that it can't be used for production, anyway.

The addition of a local testing client comes after Amazon added a new "Geo Library" to the tech last week. This high-level library allows developers to create geospatial data items such as latitude and longitude in their application, leaving the creation and maintenance of associated hash keys, range keys, and indexes up to the library.

The two moves highlight how Amazon is continuing to develop its cloud databases despite various grumblings from people that a remotely-delivered database is a very bad idea. Unless, that is, you are shoving all of your information into the AWS cloud by default. ®
