20. Copyright Elasticsearch Inc 2014. All rights reserved. Suggestions Copyright Elasticsearch Inc 2014. All rights reserved.
21. Copyright Elasticsearch Inc 2014. All rights reserved. Basic terms •  Index –  Logical collection of data; might be time based –  Analogous to a database •  Sharding –  Split logical data over several machines –  Write scalability –  Control data flows •  Replication –  Read scalability –  Removing SPOF
22. Copyright Elasticsearch Inc 2014. All rights reserved. Elasticsearch Use Case Overview: Product Catalog Analytics
23. Copyright Elasticsearch Inc 2014. All rights reserved. Analytics •  Aggregation of information •  Facets are one dimensional –  Categories/brands/material of all results of this query •  Questions are multidimensional –  Average revenue per product category per day •  Elasticsearch 1.0 has aggregations –  Nested facets –  Basic stats (mean, min/max, std dev, term counts) –  Significant terms, Percentiles, Cardinality estimations
24. Copyright Elasticsearch Inc 2014. All rights reserved. Create knowledge from data •  Orders –  How many orders were created every day in the last month? –  How many orders were created per state per day in the last month? •  Revenue –  What is the average revenue per shopping cart? –  What is the average shopping cart size per order per hour? •  Tip: bring together multiple sources of data, especially time-series data, then compare
25. Copyright Elasticsearch Inc 2014. All rights reserved. Ecosystem •  Plugins –  Many third party plugins available •  Clients for many languages –  Ruby, python, php, perl, javascript, (.NET coming) –  Scala, clojure, go •  Kibana •  Logstash •  Hadoop integration

47. Copyright Elasticsearch Inc 2014. All rights reserved. FISL 15 Talk Preview Community 2.0: Beyond Using Software Livre
48. Copyright Elasticsearch Inc 2014. All rights reserved. Software Livre in Brasil is Huge •  FISL is the world’s largest open source software conference •  Government regulations on use of software livre have been model for other nations •  Few know what is happening in Brasil
49. Copyright Elasticsearch Inc 2014. All rights reserved. Why is there a disconnect? •  Language barriers •  Emphasis in Brasil on usage vs. contribution – 2007 survey by Brasilian Ministry of Science and Technology found that only 14% of respondents were creating software livre – Only 33% of respondents made their source code available publicly
50. Copyright Elasticsearch Inc 2014. All rights reserved. Why does it matter? •  Software livre as economic engine – Crowd sourced platform for innovation in R&D – Distributed project work environment prepares workers for life in a distributed team – Show the world Brasil is a global player in software development •  Sharing is fundamental to human nature & our success as learners
51. Copyright Elasticsearch Inc 2014. All rights reserved. Ways to Contribute – Code, Code, Code •  Release works under a livre license – Source code developed for your own use – Code derived from other livre works – “giving back” •  Testing – Write test suites – Perform QA testing •  This can be as simple as filing a bug report
52. Copyright Elasticsearch Inc 2014. All rights reserved. Ways to Contribute – Beyond Code •  Translation – Software documentation, How To’s & tutorials •  Software localization, a.k.a. l10n •  Writing new articles in BR-PT to help others Fun fact: there are 12 volunteers on the BR- PT translations team for Mozilla’s Developer Network
53. Copyright Elasticsearch Inc 2014. All rights reserved. More Ways to Contribute •  Installfests •  Events to teach people to use software livre •  Giving talks about livre software tools, development methodologies and ideologies
54. Copyright Elasticsearch Inc 2014. All rights reserved. Advocacy Proudly use software livre, and ask others to do the same
