The highspeed serializer for Java environments Lightning is moving from being a Github hosted project onwards to the Apache Software Foundation. Lightning will move on to a sub-project in Apache DirectMemory but will still be usable separately. You can follow the actual state using the issue tracker: https://issues.apache.org/jira/browse/DIRECTMEMORY-102

Lightning is a custom implementation of a high performance and low latency serialization algorithm for Java. It uses JVM internal techniques and tricks to speed up reading, writing, instantiation and filling of Java Objects.
