The Morning Paper

DECEMBER 8, 2019

At the start of November I was privileged to attend HPTS (the High Performance Transaction Systems) conference in Asilomar. On the last morning of the conference Daniel Bittman presented some of the work being done in the context of the Twizzler OS project to explore new programming models for NVM.

Several system architectures were designed that implement Byzantine Fault Tolerance. The bitcoin network works in parallel to generate a chain of Hashcash style proof-of-work (also known as CPU Cost Function, Client Puzzle, Computational Puzzle or CPU Pricing Function).

Another problem is that a design control, intended to mitigate a failure mode, may not work as intended. Collecting some critical metrics at one second intervals, with a total observability latency of ten seconds or less matches the human attention span much better. Hence, one way to reduce risk is to make systems more observable.

In that scenario, the system would need to deal with the data propagation latency directly, for example, by use of timeouts or client-originated update tracking mechanisms. We started seeing increased response latencies and leader servers running at dangerously high utilization.

A few years ago, we decided to address this complexity by spinning up a new initiative, and eventually a new team, to move the complex handling of user and device authentication, and various security protocols and tokens, to the edge of the network, managed by a set of centralized services, and a single team.

As we will see, QUIC and HTTP/3 indeed have great web performance potential, but mainly for users on slow networks. If your average visitor is on a fast cabled or cellular network, they probably won’t benefit from the new protocols all that much. Two-way latency is often called round-trip time (RTT).

It also, however, takes a full network round trip to complete before anything else can be done on a connection. and lower), this typically takes two network round trips.

With these requirements in mind, and a willingness to question the status quo, a small group of distributed systems experts came together and designed a horizontally scalable distributed database that would scale out for both reads and writes to meet the long-term needs of our business. This was the genesis of the Amazon Dynamo database.
