although i'm not the authority to answer, i would probably subclass Engine and makeing it multi-sub-engine. Don't know how diff.dialects will be tackled though.. e.g one db is sqlite for quick and dirty caching, another is oracle for secure back-storage, etc. Also no idea how would u "synchronise" the db-responses, i.e. when to consider a transaction ready - when 1st db is ready, or when last db is ready etc. Same for errors - if one db throws and others do not.. i guess this can be ery usable also for full-replication mechanisms. svil --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
