Because the BDR sequences rely on all the other BDR machinery I suspect that'd be a pretty big thing to review and follow for someone who doesn't know the BDR code. Do you think it'd be simple to provide a blocking, transactional sequence allocator via this API? i.e. gapless sequences, much the same as typically implemented with SELECT ... FOR UPDATE on a counter table. It might be more digestible standalone, and would be a handy contrib/ example extension demonstrating use of the API. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
