Adding Social Network Features to a PHP App with Neo4j

Hi,

Thanks for reading the article.

  1. No there is no magic, the suggestions are the nodes that you tell Cypher to return, you can also increase the relationship depth to provide friendOfFriend or friendOfFriendOfFriend suggestions.
    Neo4j provide algorithms and it is working very well. However it is a graph database so its purpose is data store and lookup which is not data analysis. You can btw run advanced analysis like explained in this presentation : http://www.slideshare.net/bachmanm/recommendations-with-neo4j-fosdem-2015
  2. Performance is always relative to how optimized is your model and how optimized are your queries. The Neo4j has better performance however when the graph can fit in memory, meaning that it is usual to have at least 16go memory reserved for the Java heap of the Neo4j server.
    Clasterization or clusterization ? Neo4j Enterprise has an HighAvailibility mode, more informations in the documentation.
  3. Currently, no, the fulltext feature are possible but are using an index that will be deprecated in the future. So before Neo4j 2.3 is released, ES is a common add-on we use with neo4j.
