As your data grows, the need to establish proper indexes becomes critical to performance. MongoDB supports a wide range of indexing options to enable fast querying of your data, but what are the right strategies for your application?
In this talk we’ll cover how indexing works, the various indexing options, and use cases where each can be useful. We'll dive into common pitfalls using real-world examples to ensure that you're ready for scale.
Webinar slides: MORE secrets of ClickHouse Query Performance. By Robert Hodge...Altinity Ltd
Webinar May 27, 2020
ClickHouse is famously fast, but a small amount of extra work makes it much faster. Join us for the latest version of our popular talk on single-node ClickHouse performance. We start by examining the system log to see what ClickHouse queries are doing. Then we introduce standard tricks to increase speed: adding CPUs, reducing I/O with filters, restructuring joins, adding indexes, and using materialized views, plus many more. In each case we show how to measure the results of your work. There will as usual be time for questions as well at the end. Sign up now to polish your ClickHouse performance skills!

Presented on December ClickHouse Meetup. Dec 3, 2019
Concrete findings and "best practices" from building a cluster sized for 150 analytic queries per second on 100TB of http logs. Topics covered: hardware, clients (http vs native), partitioning, indexing, SELECT vs INSERT performance, replication, sharding, quotas, and benchmarking.

데브시스터즈 데이터 레이크 구축 이야기 : Data Lake architecture case study
이 세션에서는 데브시스터즈의 Case Study를 통하여 Data Lake를 만들고 사용하는데 있어 요구 되는 사항들에 대해 공유합니다. 여러 목적에 맞는 데이터를 전달하기 위해 AWS 를 활용하여 Data Lake 를 구축하게된 계기와 실제 구축 작업을 하면서 경험하게 된 것들에 대해 말씀드리고자 합니다. 기존 인프라 구조 대비 효율성 및 비용적 측면을 소개해드리고, 빅데이터를 이용한 부서별 데이터 세분화를 진행할 때 어떠한 Architecture가 사용되었는지 소개드리고자 합니다.
Webinar: Strength in Numbers: Introduction to ClickHouse Cluster PerformanceAltinity Ltd
Webinar, April 29, 2020
ClickHouse clusters apply the power of dozens or even hundreds of nodes to vast datasets. In this webinar we'll show you how to use the basic tools of replication and sharding to create high performance ClickHouse clusters. We'll study the plumbing of inserts into sharded datasets and how to determine the correct number of shards for your desired writes. We'll similarly look at distributed queries and show how to scale read capacity to desired levels using replicas. Finally, we'll look at techniques for scaling up both shards and replicas to accommodate growth in your dataset.
Disaster Recovery Cookbook - Secret recipes for hybrid-cloud success.
Digital era make organizations must depend on system to operate, but sometime organizations facing the downtime and data loss which are expensive threats.
In this webinar you will learn how to selecting the right solution to protect, move, and recover mission-critical application with near 0% data loss in cost-effective model.
All about Zookeeper and ClickHouse Keeper.pdfAltinity Ltd
ClickHouse clusters depend on ZooKeeper to handle replication and distributed DDL commands. In this Altinity webinar, we’ll explain why ZooKeeper is necessary, how it works, and introduce the new built-in replacement named ClickHouse Keeper. You’ll learn practical tips to care for ZooKeeper in sickness and health. You’ll also learn how/when to use ClickHouse Keeper. We will share our recommendations for keeping that happy as well.
No sétimo episódio da série sobre Node.js vamos conhecer um dos core modules mais importantes da plataforma, responsável por implementar o protocolo HTTP.
Vamos criar um roteador de requisições, implementando o back-end utilizado na série sobre AngularJS.

AngularJS $http Interceptors (Explanation and Examples)Brian Swartzfager
Slide deck from a 10-minute lightning talk on AngularJS $http interceptors (what they are, how to write them, and what you can use them for) presented at the AngularJS Meetup hosted by Difference Engine in Washington DC on Feb. 18, 2015.
Vamos falar sobre o objeto process, abordando algumas de suas principais informações como: pid, title, arch, platform, memoryUsage, uptime, env e muito mais.
Vamos começar interagindo com os argumentos passados pela linha de comando e depois por meio do teclado. Falaremos também sobre os 3 tipos de standard stream: input, output e error.
Por fim, aprenderemos a abortar o processo e a tratar eventos como exit e uncaughtException.
No sexto episódio da série sobre Node.js vamos conhecer um dos core modules mais antigos da plataforma, responsável por viabilizar a comunicação de dados com base no protocolo TCP.
Para isso, vamos desenvolver um chat, aprendendo a conectar clientes ao servidor, trocando mensagens e tratando os principais eventos como o connect, data e end.

Vamos falar sobre o tipo Date, abordando a forma de armazenamento interno, explicando o que é a era Unix, a partir de onde as datas são calculadas, e também as 4 formas de criar um Date, a partir de sua função construtora.
Além disso, veremos os formatos RFC 2822 e também o ISO 8601, ambos aceitos na criação de uma data a partir de uma String e por fim estudaremos algumas operações da API de Date.
Abordaremos a criação de expressões regulares, ou simplesmente RegExp, utilizando caracteres especiais, grupos, conjuntos, quantificadores, metacaracteres, modificadores e muito mais!
Além disso, vamos explorar também a API de RegExp e também String, falando das operações exec, test, match, split e replace.
