Hi, We've just tagged the 1.0 NEO release. NEO aims at being a replacement for use-cases where ZEO is used, but with better scalability (by allowing data of a single database to be distributed over several machines, and by removing database-level locking), with failure resilience (by mirroring database content among machines). Under the hood, it relies on simple features of SQL databases (safe on-disk data structure, efficient memory usage, efficient indexes). Release highlights: - production-ready ! - asynchronous replication across clusters, for inter-datacenter redundancy - there will be no further expensive data schema changes within the 1.x branch as there were in 0.x branch - replication performance is significantly increased - general implementation performance improved - several bugfixes What you need to know if you are used to ZODB features: - Blob API is not implemented yet. - pack's GC phase will not be implemented in NEO, it relies on zc.zodbdgc for this: http://pypi.python.org/pypi/zc.zodbdgc For more details, look at README and CHANGES included with the sources: http://git.erp5.org/gitweb/neoppod.git/blob/HEAD:/README http://git.erp5.org/gitweb/neoppod.git/blob/HEAD:/CHANGES NEO is published on pypi as "neoppod": http://pypi.python.org/pypi/neoppod Regards, -- Vincent Pelletier ERP5 - open source ERP/CRM for flexible enterprises
