Reliability

The reliability of a data storage - such as NEO - is critical. To ensure the quality of NEO design, its protocol is in the process of being formally proven through model-checking. To ensure code quality, NEO project relies on automated testing:

  • unit test checking individual method behaviour
  • functional tests checking node and cluster behaviour
  • standard ZODB test suites

Requirements

The following software is required:

  • Linux 2.6 or later
    Note: the actual requirement is on epoll, integrated in 2.5.44. There are plans to add support for other platforms, but it is not implemented yet.
  • Python 2.7 (2.7.9 or later for SSL support)
  • MySQLdb
    Note: MySQL server is currently used as a backend for NEO, with InnoDB, RocksDB or TokuDB storage engine. This was chosen as an early approach to take advantage of existing features (transactional persistent storage, basically), and will be replaced with leaner key/value storage later.
  • ZODB >= 3.10.x (Zope 2.13 or later)

History

NEO project was initiated in 2005 by Nexedi SA, a French company developing ERP5 - a Free Software ERP for small to large enterprises implemented on top of Zope - since 2001.
