Questions and Answers related to Neo4j Development
“Graph is a natural index. Everything is indexed—-nodes are connected to each other via edges. It takes constant time to locate the relevant data. To understand the constant index lookup property, let’s step back to a familiar context—the relational database. In relational database, when you lookup an indexed value, it takes constant time. Analogy is the Table of Contents (TOC) of a book, regardless of the book content thickness, it takes constant time to look up the TOC and locate a content…”
“A database is persistent, can serve multiple clients, since can scale and perform transactions, and operations that would be harder to specify or slower. Each node of the graph can have data. Each link can have data. A node can link to nodes in other graphs. Try find-shortest-path on a graph with 30,000 nodes and 280,000 connections. When I tested it yesterday it took about a tenth of a second to find a shortest path that was eight nodes long, out of millions of possible paths…”
“Graph DB would be much faster when you are interested in querying individual instances as opposed to large sets of instances. Graph DB effectively pre-joins individual records avoiding index lookups and making such query time independent of dataset size (index-free adjacency). Recursive queries that arise when exploring relationships on the same class (e.g. friend of a friend) are easier with a traverse operation available in graph query languages…”
“There are two types of graph databases. Graph engines for transaction processing , e.g. OrientDB and Neo4J and graph analytic engines. JanusGraph is an open source transaction graph database with Apache 2.0 license. It is a fork of TitanDB and uses Cassandra or HBase as a storage engine with optional indexing in Solr and graph analytics in GraphX. JanusGraph is distributed and can handle large volumes of data. Unlike Neo4J it uses the concept of an adjacency list as storage whereas Neo4J uses a doubly linked list…”
