There is another case where you have so many stateless servers that an individual database shard can't handle the number of connections. For example, if you have 1000 frontends that all need to talk to a sharded database and you only want to support 100 connections per shard you need to put concentrators inbetween the frontend tier and the database to reduce the number of connections. |
