Having worked on supercomputers in the 1980s, as an evangelist for Java development in the 1990s, and today, as an OpenStack board member and leader for Cisco’s open source initiatives, this conversation between Shay and Lew will surface perspectives on the future of open source for developers and enterprises.
How many shards should I have? How many nodes should I have? What about replicas? Do these questions sound familiar? The answer is often ‘it depends’. This talk will outline the factors that affect sizing and walk you through a quantitative approach to estimating the configuration and size of your cluster.
This talk will focus on the ways to leverage the Elastic Stack to build tools for your sales and marketing teams. We will demo some internal tools we’ve built including cohort analysis of Salesforce data, leveraging Watcher to alert on large data changes, and more.
Netflix messages millions of customers a day across many channels – email, push notifications, text, voice calls, etc – via its messaging platform: a distributed system made up of a series of separate applications. Learn how they use Elasticsearch for higher message deliverability and operational excellence.
Salesforce built a plugin to the Elastic Stack – called ELF – that enables the collection of Salesforce log data. Come learn how it allows businesses to easily report on user activity in Salesforce and gain insights into organizational usage trends and user behavior.
If you’re using Elasticsearch on Windows or Azure, this session is a must-attend. Our .NET team will demo our Azure Marketplace offering & give a sneak preview of the MSI-based installer. In closing we'll give an overview of everything new in NEST and Elasticsearch.NET 2.0, the official .NET clients.
The Beats project has evolved from just one Beat – Packetbeat – to several Beats, many of which are written by users like you. In this talk, join Beats core developers Nicolas and Steffen in their whirlwind attempt at creating a new Beat, live, from scratch!
Get insights and ask questions about the ever-evolving journey of Elastic engineering. This talk will cover what changed as we grew from 15 to 150+, how we operate as a global distributed team and communicate effectively, as well as what guides us in developing the software you know and (hopefully) love.
Mayo Clinic is bringing real-time clinical decision making to the point of care with a vertical application they built using the cloud, Elasticsearch, and D3 widgets. Hear how this application allows physicians to find similar patients and explore what-if scenarios using outcome and intervention parameters.
Today the default scoring algorithm in Elasticsearch is TF/IDF. This default will change to BM25 once Elasticsearch switches to Lucene 6. In this talk, Britta will tell you all about BM25 – what it is, how it differs from TF/IDF and other scoring techniques, and why it might be the better default going forward.
Learn how Elastic uses the Elastic Stack throughout the company — from how and where its data stores are built to best practices for production clusters, as well as what is built on premise and when it leverages its Cloud service.
Learn how Giant Oak and its partners use Elastic to help power work combating human trafficking, financial fraud, abuse of prescription drugs, and the trade in endangered species.
This talk will cover everything you ever wanted to know about geo and Elasticsearch! Get advice on field mapping strategies, learn about geo aggregations and visualizations for exploratory spatial data analysis, as well as get insights into new spatial data structures being added to Lucene and Elasticsearch.
A build system is an important tool which provides robust testing and distribution. While unseen by most users, it’s central to any successful software. Late last year, Elasticsearch switched to use Gradle. This talk will explore the history and motivations behind the switch, as well as further improvements now made possible.
The Internet Archive’s Wayback Machine has collections that range in size from billions of archived web pages, to millions of scanned books, down to 10,000 quite-popular Grateful Dead concert recordings. See how Elasticsearch glues everything together and hear some lessons learned along the way.
It's not Julia Child or Gordon Ramsay, but this cookbook is worth it. Come hear Martin Smith – co-author of the Chef Community Cookbook for Elasticsearch – present a hybrid between automating Elasticsearch installation and configuration with Chef, and re-writing the open source Chef cookbook the last 12 months.
Zymergen has developed a new, industrialized process to create microbes capable of fermenting chemicals, pharmaceuticals and more. Success depends on insights gleaned from large volumes of possible DNA modifications. This talk will cover how Elasticsearch powers this revolution in scientific data analysis.
Fast search usually boils down to data organization, which is why Elasticsearch is based on an inverted index. But sometimes speed comes from clever algorithms. Last year we looked at four such algorithms, but there are dozens more. In this talk we'll explore a new set of interesting algorithms in Elasticsearch.
