Consensus with Raft Algorithm
When we talk about consensus in a distributed system, we talk about a system consisting of multiple machines that act as one state machine yet capable of surviving failures of some of the system nodes. Consensus algorithms are designed to enforce all distributed nodes have the same state so that the distributed system can tolerate…

About Google’s Dataflow Model
In this post I am trying to understand the Google’s Dataflow Model, a data management and manipulation framework used for dealing with unbounded and unordered datasets. A lot of the data is being constantly produced today and has no “maximum size”, in other words the amount of such data is constantly increasing, and therefore modern…

Understanding ZooKeeper
ZooKeeper is not new, it has been around for quite some time now, yet I feel like not many people who use it in one way or another do understand what it is. ZooKeeper is used by so many distributed systems at the moment that it became a crucial part of the distributed computing, and…

Graph Processing at Facebook Scale
I will start with a little note on large scale graph processing, as described in the paper “One Trillion Edges: Graph Processing at Facebook Scale”. Graph processing tasks are very common in analyzing various kinds of data, such as network topology of interconnection of people. Social media imposes challenges for such systems and algorithms due…
