Initial release of the implementation that is based on AWS SDK 2.x. This has the same functionality as version 1.0.0, but uses the DynamoDB client classes from the more recent AWS API.
This library provides a DynamoDB-backed persistence mechanism (feature store) for the [LaunchDarkly Java SDK](https://github.com/launchdarkly/java-client), replacing the default in-memory feature store.

This version of the library requires at least version 2.1 of the AWS SDK for Java, and at least version 4.6.0 of the LaunchDarkly Java SDK. The minimum Java version is 8 (because that is the minimum Java version of the AWS SDK 2.x). If you need to use Java 7, or if you are already using AWS SDK 1.x for some other purpose, you can use the 1.x releases of this library (which are developed on the "aws-v1" branch of the repository).

To reduce traffic to DynamoDB, there is an optional in-memory cache that retains the last known data for a configurable amount of time. This is on by default; to turn it off (and guarantee that the latest feature flag data will always be retrieved from DynamoDB for every flag evaluation), configure the store as follows:

## About LaunchDarkly

* LaunchDarkly is a continuous delivery platform that provides feature flags as a service and allows developers to iterate quickly and safely. We allow you to easily flag your features and manage them from the LaunchDarkly dashboard. With LaunchDarkly, you can:
71
67
* Roll out a new feature to a subset of your users (like a group of users who opt-in to a beta tester group), gathering feedback and bug reports from real-world use cases.
72
68
* Gradually roll out a feature to an increasing percentage of users, and track the effect that the feature has on key metrics (for instance, how likely is a user to complete a purchase if they have feature A versus feature B?).
73
69
* Turn off a feature that you realize is causing performance problems in production, without needing to re-deploy, or even restart the application with a changed configuration file.
74
70
* Grant access to certain features based on user attributes, like payment plan (eg: users on the ‘gold’ plan get access to more features than users in the ‘silver’ plan). Disable parts of your application to facilitate maintenance, without taking everything offline.
* LaunchDarkly provides feature flag SDKs for a wide variety of languages and technologies. Check out [our documentation](https://docs.launchdarkly.com/docs) for a complete list.
