I have a question for experts in Hoodie and/or other similar projects (like Meteor):

How are database connections managed? If every client (browser) basically talks nearly directly to the database, don't you end up with of thousands of database connections?

Large number of connections is not a problem by itself, and servers like nginx handle them well, but I am not aware of a database which will feel comfortable being exposed this way. MongoDB, for example, really starts struggling with 2K+ connections. PostgreSQL can barely handle a hundred.

Is this why CouchDB is used? Is connection pooling used on the server? Or maybe the connections are short-lived and never persistent? Basically, how does this work with large number (say, 10K) of concurrent visitors?

Thanks!
