Summary
In this chapter, we started with exploring AWS-provided Java libraries, that is, the Transac-
tion library and the Geo library. The Transaction library enabled multi-item atomic opera-
tions, where we can simply use the API and perform the operations without any doubts
about inconsistent states. Geo library enabled us to easily save geographical points and
query them with simple APIs, such as Query radius and Query rectangle.
We also listed down well-known language-specific libraries to enable developers to manip-
ulate DynamoDB data with a language of their own choice. Similarly, we also explored
some tools that would help us in testing DynamoDB locally, auto-scaling the tables, and
archiving data on AWS S3.
In our next chapter, we are going to see how DynamoDB can be used to back mobile ap-
plications and how it will help your mobile applications to scale easily.
