My understanding is that pymongo has connection pooling builtin. -> http://api.mongodb.org/python/current/api/pymongo/connection.html
Also, it appears that an addition to the cache method described by Massimo enables the use replica sets as well. You still need to handle AutoReconnect exceptions when the master is lost. -> http://api.mongodb.org/python/current/api/pymongo/errors.html#pymongo.errors.AutoReconnect def make_connection(): from pymongo import Connection connection = Connection('localhost', 27017, replicaset="setName") return connection connection = cache.ram('mongodb',make_connection,None) Regards, Daniel On Aug 14, 11:25 am, Karthik <[email protected]> wrote: > I'm still looking for a solution to simulate connection pooling, any > responses would be great - thanks! > > On Jul 21, 4:53 pm, Karthik <[email protected]> wrote: > > > > > > > > > Hi Massimo, > > > Thanks for this.
