Blogpost: Large-scale graph partitioning with Apache Giraph
Hi Giraphers, Recently, a few internal Giraph users at Facebook published a really cool blog post on how we partition huge graphs (1.15 billion people and 150 billion friendships - 300B directed edges). https://code.facebook.com/posts/274771932683700/large-scale-graph-partitioning-with-apache-giraph/ Avery

Great to have you in the PMC! On 04/22/2014 05:43 PM, Avery Ching wrote: Maja has been working on Giraph for over a year and is one of our biggest contributors. Adding her to the Giraph PMC in recognition of her impressive work is long overdue. Some of her major contributions include composable computation, sharded aggregators, Hive I/O, support for massive messages, as well as lots of bugfixes and code reviews. She has also been responsible for several major performance improvements (i.e. message store specialization, message cache improvements, etc.). We are very lucky to have her working with us on this project. Avery
