Database Reference
In-Depth Information
Summary
In this chapter, we have seen the design specifications of DynamoDB, various techniques
like a quorum approach, gossip protocols, ring membership, and Merkle trees, and their im-
plementation and benefits in developing such a brilliant system. We can see the efforts put
in by the Amazon engineering team and their focus on each and every minute detail of ar-
chitecture and its execution.
As I had said earlier, DynamoDB was the real inspiration for many NoSQL databases, such
as Riak and Cassandra. Now, that you have understood the architectural details of Dy-
namoDB, you can check out the architecture of previously mentioned databases and see the
similarities and differences.
This chapter was an effort to simplify the information given by Amazon in its white paper,
but as time flies, there would have been many changes in its architecture, and to know
more about it, we would have to wait to hear it from Amazon.
I am sure if you are a real technology fan, then after reading this chapter, you would have
definitely fallen in love with DynamoDB. In the next chapter, we are going to talk about
the best practices one should follow in order to get the maximum benefit out of Dy-
namoDB and save some money too.
