Neo4j Milestone 1.9.M04 released by Michael Hunger.
From the post:
Today we’re happy to announce Neo4j 1.9.M04, the next milestone on our way to the Neo4j 1.9 release.
For this milestone we have worked on further improvements in Cypher, resolving several issues and continued to improve performance.
Something many users has asked for is Scala 2.10 support which we are providing now that a stable Scala 2.10 release is available.
There were some binary changes in the Scala runtime so by adopting to these, Cypher became incompatible to Scala 2.9. Please ping us if that is an issue for you.
In the Kernel we finally resolved a recovery problem that caused the recovery process to fail under certain conditions.
Due to a report from Jérémie Grodziski we identified a performance issue with REST-batch-operations which caused a massive slowdown on large requests (more than thousand commands).
Solving this we got a 30 times performance increase for these kinds of operations. So if you are inserting large amounts of data into Neo4j using the REST-batch-API then please try 1.9.M04 if that improves things for you.
If you are tracking development of Neo4j, a good time to update your installation.
