Graph database Neo4j in News

New Neo4j platform gives developers a set of tools for building enterprise graph applications

Graph database leader Neo4j has launched a new platform for developers to build graph-based applications using a common set of services. Breaking the announcement at its GraphConnect conference in New York, Neo4j said the new platform will help the graph databases connect to various enterprise systems allowing developers to build applications more quickly. Until now, customers were forced to create their own architecture to manually connect to these systems.

Neo4j releases Cypher for Apache Spark

At its ongoing GraphConnect conference, Neo4j announced a new initiative to support the design and execution of graph queries in the Apache Spark environment. Neo4j released an early version of Cypher for Apache™ Spark® (CAPS) language toolkit to the openCypher project. This contribution will allow big data analysts to incorporate graph querying in their workflows, making it easier to bring graph algorithms to bear, dramatically broadening how they reveal connections in their data.  Developers of Spark applications now join the users of Neo4j, SAP HANA, Redis Graph and AgensGraph, among others, in gaining access to Cypher, the leading declarative property graph query language. This also expands the tooling available to any developer, under Apache 2.0 licenses from the openCypher project.

Neo4j 3.3 released with improved performance and security

Neo4j has announced its latest release – Neo4j 3.3. With Neo4j 3.3 write performance has improved with on average 50% compared to Neo4j 3.2, making it possible to ingest more data in less time. Bulk writes at initial graph creation reduces the memory footprint by up to 40%. The new Cypher Slotted Runtime results in faster queries while using one third of the memory compared to the Neo4j 3.2 Cypher Runtime. On security front, Neo4j 3.3 introduces new support for intra-cluster encryption, including multi-DC cluster communication encryption. The new version also brings new kernel improvements as it now allows key configuration parameters to be changed on the fly, without needing to recycle a database instance.

Microsoft brings real time health reporting to Windows Dev Center

Microsoft will now offer near real time health reporting in its Windows Dev Center, thus helping developers to quickly fix stability issues in their apps. If you have joined the Dev Center Insider Program, the Health report’s 72H view in Dev Center now shows data for crashes, hangs, memory failures and JavaScript exceptions within minutes of those events. Previously, this data was available only after several hours. Microsoft said it will soon bring this feature to all Dev Center users.

Microsoft adds new feature called Review Insights in Windows Dev Center dashboard

In Windows Dev Center, under the Review Reports, Microsoft is introducing a new feature called Review insights. Review insights uses machine learning to classify new app reviews, even non-English reviews, into one of 12 pre-defined categories. This will help developers to quickly understand customer sentiment by filtering their app’s reviews by category. Developers can also apply additional filters, such as OS version or rating, to further isolate issues and find actionable feedback.
