Web2Day Nantes 2015 - workshop

Elasticsearch and Kibana workshop
Talk given in Nantes, France: http://web2day.co/en/speakers/david-pilato-2/
Let’s start to discover elasticsearch and Kibana.

For this session, you will need:

* a JVM
* a browser

We will install elasticsearch, Kibana and Marvel and will use that tools to:

* index/update/get/delete documents
* search
* compute
* build dashboards to make sense of marketing data
* snapshot and restore our data

4. www.elastic.co Copyright Elastic 2015 Copying, publishing and/or distributing without written permission is strictly prohibited 4 fundamentals elasticsearch
5. www.elastic.co Copyright Elastic 2015 Copying, publishing and/or distributing without written permission is strictly prohibited 5 a search engine • Create indices from documents • Search in indices
6. www.elastic.co Copyright Elastic 2015 Copying, publishing and/or distributing without written permission is strictly prohibited 6 elasticsearch • Cloud based search engine • Based on Lucene • Hide Lucene complexity by exposing all services – HTTP / REST / JSON • Works with all technologies • Horizontal scaling, replication, fail over, load balancing • Blazing fast! • It’s a search engine! Not a search tool in a box!
7. www.elastic.co Copyright Elastic 2015 Copying, publishing and/or distributing without written permission is strictly prohibited 7 think document! • Change your mindset: – Forget SQL! – Index what you want to find • A document – A JSON object – Core field types (string, numbers, booleans) – Complex field types (arrays, objects) – Additional field types (geo points, geo shapes)
8. www.elastic.co Copyright Elastic 2015 Copying, publishing and/or distributing without written permission is strictly prohibited 8 organize your documents! • Documents coordinates: – index (hold setup) – type (holds mapping) – id (can be auto-generated) { "name" : "elasticsearch", "website" : "http://www.elasticsearch.com", "category" : "software", "founded_year" : 2012, "overview" : "The company behind the elasticsearch open source project", "tags" : ["search", “datastore", "analytics", "realtime", "scalability"], "location" : { "city" : "Amsterdam", "country_code" : "NL", "geo" : { "lat" : 52.370176, "lon" : 4.895008 } } }
9. www.elastic.co Copyright Elastic 2015 Copying, publishing and/or distributing without written permission is strictly prohibited 9 glossary • Node – a running elasticsearch instance (JVM process) • Cluster – a group of nodes • Shard – a part of an index – a Lucene index under the hood – primary: unique in the cluster – replica: one or more copy of the primary
