GraphConnect – a Neo4j conference

neo4jconference

We were in London to attend GraphConnect, the annual conference organised by Neo4j.
It was fantastic to meet so many people around the world enthusiastic about graph databases, and a lot of people that, like us, are prototyping/exploring Neo4j as possible alternative to relational databases.

They have announced the release of Neo4j 3.2 which promises to bring a huge improvement in term of performance; the compiled Cypher runtime has improved the speed by ~300% for a subset of basic queries and the introduction of native label indexes has also improved the write speed.

They have also added the composite indexes (that InterMine uses a lot) and the use of indexes with the OR operator. We highlighted the problem months ago on stackoverflow and we were so surprised to see it fixed. We have to update our “What we didn’t like about Neo4j” list by removing 2 items. We’re really happy about that!

It was a pleasure to attend Jesus Barrasa’s talk on debunking some RDF versus property graph alternative facts. He demoed how a RDF resource does not necessarily have to live in a triple store but can also be stored in Neo4j. Here are part1 and part2 of “Neo4j is your RDF store”, a nice post where he describes his work in more detail.

Another nice tool they have implemented is the ETL tool to import data from a relational database into Neo4j by applying some simple rules.

The solution-based talks demonstrated how Neo4j is being used to solve complex, real world problems ranging from travel recommendation engines to measuring the impact of slot machine locations on casino floors. While the topics were diverse, a common theme across their respective architectures was the use of GraphAware’s plugins, some of which are free. One plugin that looks particularly interesting is the Neo4j2Elastic tool which transparently pushes data from Neo4j to ElasticSearch.

During the conference, we discovered that there is a Neo4j Startup Program that allows to have Neo4j enterprise edition for free. Not sure if we count as a start up though!

Overall, we’re super happy with the improvements Neo4j has made, and super impressed with Neo4j’s growing community. Looking forward to meeting with Neo4j team in London, at their meetup, and sharing our small experience with the community!
