Neo4J is the most popular graph database in the NoSQL databases family. We’re using it in the Nousmotards project to store all social data through nodes and relationships. Today I am going to talk about our experience after having using it for 2 years now (take a look at directed graph if you are not really familiar with Graph Database). 1/ Our use case Nousmotards is a social network for bikers, we aim to provide valuable tools to ride, meet and share nice time with people who like motorcycling.
The Ansible meetup ended ! That was really nice for my first one. I had really great feedbacks and liked the questions when ended. More than that I met nice people after the meetup and could have interresting discussions :-). I’m really happy about it. For those who would like to review the slides, you can find them here: http://nousmotards.github.io/ansible-meetup-0915/ If you want to watch the video: http://www.infoq.com/fr/presentations/reseau-social-motard or view the PDF version here:
For a new project (will talk about it later), I needed to use Neo4J (graph database if you don’t know it yet). I tried to cover more features than the current existing Ansible roles available on Ansible Galaxy. More will come in the next weeks. I also tried to make it simple to install it and do not force dependencies at maximum. Here are parameters you can set: # Select neo4j version neo4j_package: neo4j # community version #neo4j_package: neo4j-advanced #neo4j_package: neo4j-enterprise # Neo4j spatial plugin neo4j_install_spatial: false neo4j_spatial_version: '0.
I recently played with ElasticSearch Cluster and I totally fall in love! How easy it is, everything is automatic, it works perfectly, wowwww!!! I made a little documentation on how to setup one, you can find it there. ElasticSearch is a really powerful solution and I really like working with it. If you’re searching a full text search solution, try ElasticSearch, you’ll be happy!
I really like working on ElasticSearch, so powerful, so easy to use, so scalable and so high available. I’ve found a very interresting book I bought on it. It will help you to start with ElasticSearch and answer a lot of question you may have regarding the product. If you want to buy it, take a look there.
During the last weeks I started to play with Elasticsearch, Fluentd and Kibana. I made a documentation to help on deploying it easily. As you may know, I’m an Ansible fan, so I made Ansible playbooks to deploy a complete infrastructure (server and clients). They will deploy this kind of architecture: On the client side, Fluentd clients will get syslog and Nginx logs, to send them to the Fluentd server. On the server side, a Fluentd receiver will be there to get data from other Fluentd clients.
Next Tuesday, ElasticSearch will takes place. Last meetup was very interesting and technical. I hope this one will be as good as the last one. There will be a talk from Dailymotion and an ElasticSearch Core developer. To get more informations it’s here.
