mongodb will auto promote. Caveat, (like redis if i understand correctly), is that all writes are directed to a single master (be it chosen dynamically), but reads can happen anywhere to spread the load. Also, you need to accept the distaster scenario of a "network partition" where a minority set of servers find themselves w/o a master. Example: 5 servers in datacenter #1 and 4 servers in datacenter #2. If the link between datacenters is broken, then all servers in datacenter #2 will not have a master and will be read-only until link is restored. Good part about single master is there's no chance of inconsistent data. Turns out local fail-over v.s. consistent data is a well explored area. http://blog.nahurst.com/visual-guide-to-nosql-systems I've worked w/the C++ driver to mongodb is anyone has questions. _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
