July 2011 Summaries

The webinar covered the basics of graph databases, specifically Neo4j, a popular open-source graph database. The discussion touched on various topics such as data representation, relationships between nodes, traversal methods, and performance considerations. Attendees asked questions about keys and values, best practices for programming with Neo4j, and how to work with large datasets. The webinar also highlighted the limitations of traditional relational databases compared to graph databases, which offer a more flexible and scalable way to store and query complex data.

Neo4j has released its version 1.4 "Kiruna Stol" General Availability package, featuring a new Cypher query language that provides humane syntax for graph queries, automatic indexing to manage the lifecycle of index entries, and improvements to performance, REST API, and Webadmin tools. The release includes upgrades to Lucene 3.1, support for self-relationships, and enhancements to indexes, making it the best release yet according to Neo4j's team.

It's been a week since the Neo4j 1.4 M05 release, and although the feature set has evolved positively, a potential corruption bug was discovered during testing. To address this issue, a sixth milestone is being released, which may be the last of the series for the 1.4 GA release if community feedback is positive. The milestone includes syntax changes in Cypher to make queries smaller and easier to read/write. Early adopters are encouraged to download and test the milestone thoroughly before using it in production, with a reminder to backup their data. This release aims to provide a stable foundation for the 1.4 GA release.
