For the Global GraphHack 2019, we extended JMeter to support the Bolt protocol and do load testing on Cypher queries.

BANGALORE, October 10, 2019 – Softlink Information Systems and GraphAware are pleased to announce that they have entered into a global strategic partnership, combining Softlink’s industry leading database consulting services with GraphAware, the leading Neo4j ISV and consulting practice, and the creators of Hume, a cutting-edge Graph-Powered Insights Engine.With knowledge graphs playing an increasingly critical role for enterprises to move to the next level of information analytics, companies recognize that they need to accelerate the development of knowledge graphs to ensure they remain on the competitive vanguard. The Softlink-GraphAware partnership brings together deep skills in business and technology strategy, driven...

We have already blogged about fulltext search available in Neo4j 3.5. The list of available analyzers covers many languages and fits various use cases. However once you expose the search to real users they will start pointing out edge cases and complain about the search not being google-like.Speakers of languages using accents in their written form quite often leave out the accents. This has various reasons, the most common ones are historical, when different character encodings caused problems and users find it hard to change their habits using a different default keyboard layout (e.g. en_US); switching the layout just for...

Do you use D3 for data visualisation and either you are considering, or already using it also for graph visualisation? Keep in mind that D3 uses SVG for rendering. While it is the easiest to work with API for drawing 2D graphics on the Web, its downside is that the browser keeps the entire DOM tree of vector elements in memory, even for elements that are effectively invisible. You might hit a performance drop with complex graphics, specifically for graph visualisation when you try drawing graphs larger than ~1000 nodes, or even less with complex SVG effects.At this time you...

The Cypher query planner is quite advanced and mature, and you can mostly rely on it to pick the best plan for your query. However, there are rare cases, or bugs, that might want you looking for ways to influence that plan. This article demonstrates practical usage of an index hint. Note that all queries were tested against Neo4j Enterprise 3.5.8The graph modelThis is the relevant portion of the graph model that is sufficient to demonstrate the issue.Simple enough- we have many tweets, and tweets have keywords.Our graph has two indexes, one on the value of the Keyword, and the...

Neo4j Desktop, part of the Neo4j Graph Platform, is a client application that installs on your desktop OS. It lets you get started quickly by downloading and installing the enterprise edition, and supported plugins. You can group related graphs and applications under a Project. You can also build single-page web applications that run within Neo4j Desktop and have access to these services provided by Neo4j Desktop. There are a number of apps available at https://install.graphapp.io/In this blog post, we will build a very simple graph app using vanilla javascript.All code in this blog post is available at https://github.com/aldrinm/simple-graph-app and https://github.com/aldrinm/simple-graph-app-npmHello,...

“Lateral thinking” was a big topic back in 2004 when I was in the Network Operations Center (NOC) business; one definition is: “(lateral thinking) is the solving of problems by an indirect and creative approach, typically through viewing the issue in a new and unusual light.”If it works, don’t touch itBut the world of NOC operations, and generally IT Operations was anything but creative, not because we didn’t appreciate innovation per se, but because we valued reliability, consistency an uptime above all things, and those outcomes are the result of a long tradition in IT of approaching change, the natural...

This is the second of a two post series on monitoring the Neo4j graph database with popular enterprise solutions such as Prometheus and Grafana. Monitoring the status and performance of connected data processes is a crucial aspect of deploying graph based applications. In Part 1 we have seen how to expose the graph database internals and custom metrics to Prometheus, where they are stored as multi-dimensional time series.It is now time to query those metrics and render results in a beautiful, integrated Grafana dashboard. This will help you establish 24/7 monitoring and alerting of your Neo4j setup so that you...

Database Monitoring is a crucial aspect of any application deployment. After all, databases manage data and sit quite down in the stack. They are robust pieces of software, but their setup and maintenance need care and attention since any problem has the potential to be disruptive to business.
