From Wikipedia: Open notebook is the practice of making the entire primary record of a research project publicly available online as it is recorded. There is no 'insider information'. It is the logical extreme of transparent approaches to research and explicitly includes the making available of failed, less significant, and otherwise unpublished experiments.
Each hive sends in data every five minutes - 288 times a day. Each hive inserts over 100,000 rows a year into the Operational Database.
