Data Key Caching now gets support by AWS Encryption SDK

Data Key Caching allows you to reuse the data key that secures your data instead of creating a new data key for each encrypted operation. Data Key caching will give you the advantage you helping you to stay within the service limits of the application scales, it improves performance and minimizes cost. AWS Encryption SDK is a library of encryption that will make it easy for you to apply the encryption best practices to the applications. This will allow you to focus more on the core part of the functionality of the application instead of figuring on how to encrypt and decrypt the data. You should use this feature cautiously because Cryptographic discourages excess use of data keys. Use it only when it is required to increase the performance goals.
