* For PostgreSQL the default allowed max connection is 100. If we have to many products and multiple servers then we can reach this limit very easily because we create 5 pool for each product by default. E.g.: 2 servers (load balanced) with a shared database which contains 10 products and 1 config database will create maximum (10 + 1) * 5 * 2 = 110 pool. In this case we reach the default connection limit and PostgreSQL will not allow more connections. * For SQlite we use the NullPool which doesnt pool connections.
