こんにちわ、7月に入社したばかりの@emorinsです。 題名の通りですが分散データベース『Apache Cassandra』を紹介したいと思います。 少し前はHadoop(とHBase)と比較されることの多かったCassandraですが、最近はHadoopの人気に押されつつあるようにも感じます。 しかし、CassandraとHadoopは特徴が異なり、よく言われるのがCassandraはリアルタイム処理に向き、一貫性のかわりに可用性を重視し、またHadoopとは違って単一障害点もありません。 今日はそんなHadoopとは違った魅力のある分散データベース『Apache Cassandra』をはじめてみましょう。 目次 Cassandraとは アーキテクチャ Cassandraの特徴 コンシステンシレベル データモデル MemtableとSSTable セットアップ storage-conf

Metalsmith Part 3: Refining Our Tools | Robin Thrift
Last time we took a dive into collections and Metalsmiths internals. This time we are going to refine our script and even develop our own little plugin. Without wasting any time, let’s get started! ###Writing Plugins I am going to start this tutorial off with a little plugin, that will save us a time, and automate our build process further. In order to render our posts correctly, we have to set ev
Thrift: The Missing Guide
Thrift is a software framework for scalable cross-language services development. It combines a software stack with a code generation engine to build services that work efficiently and seamlessly between C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa, JavaScript, Node.js, Smalltalk, and OCaml. Thrift is clearly abundant in features. What is sorely lacking though is good documentatio
Apache Thrift - PHP library
Using Thrift with PHP Thrift requires PHP 7.1 Thrift makes as few assumptions about your PHP environment as possible while trying to make some more advanced PHP features (i.e. APCu cacheing using asbolute path URLs) as simple as possible. To use Thrift in your PHP codebase, take the following steps: Copy all of thrift/lib/php/lib into your PHP codebase Configure Symfony Autoloader (or whatever you

How Uber Engineering Evaluated JSON Encoding and Compression Algorithms to Put the Squeeze on Trip Data
For compression, we put three lossless and widely accepted libraries to the test: Snappy zlib Bzip2 (BZ2) Snappy aims to provide high speeds and reasonable compression. BZ2 trades speed for better compression, and zlib falls somewhere between them. Testing Our goal was to find the combination of encoding protocol and compression algorithm with the most compact result at the highest speed. We teste
Metalsmith Part 1: Setting Up the Forge | Robin Thrift
In my last article I gave a brief introduction to Metalsmith, a simple, pluggable static site generator written in JavaScript. In this tutorial I want to show, what a basic folder structure for Metalsmith could look like and we will also set up the basic build script. The source code for this tutorial can be found here. You will need Node.js and NPM. To find out, how to install them check the offi
Metalsmith Part 2 : Shaping The Metal | Robin Thrift
In my last post I talked about the basic structure of a Metalsmith project and showed you the basics, like templating and plugin installation/configuration. This time we are going to delve further into the subject and look at some Metalsmith internals. Content Types Firstly we will need to determine, what kind of content we want to create, or rather, its type. Wordpress by default gives you two op
Protocol Buffers, Avro, Thrift & MessagePack - igvita.com
By Ilya Grigorik on August 01, 2011 Perhaps one of the first inescapable observations that a new Google developer (Noogler) makes once they dive into the code is that Protocol Buffers (PB) is the "language of data" at Google. Put simply, Protocol Buffers are used for serialization, RPC, and about everything in between. Initially developed in early 2000's as an optimized server request/response pro

Do you really know why you prefer REST over RPC? By Arnaud Lauret, May 10, 2015 A few weeks ago I’ve seen an interesting flock of tweets initiated by this question: This question and the tweets that followed put my brain on quite an animated discussion… After this internal discussion, I realized that this question (and all the tweet debate that follows it) could help me highlight a dark corner of
