This example uses a global (gasp) :class:`GreenPool <eventlet.greenpool.GreenPool>` to control concurrency. If we didn't have a global limit on the number of outgoing requests, then a client could cause the server to open tens of thousands of concurrent connections to external servers, thereby getting feedparser's IP banned, or various other accidental-or-on-purpose bad behavior. The pool isn't a complete DoS protection, but it's the bare minimum. This example uses a global (gasp) :class:`GreenPool <eventlet.greenpool.GreenPool>` to control concurrency.

The db_pool module is useful for managing database connections. It provides three primary benefits: cooperative yielding during database operations, concurrency limiting to a database host, and connection reuse. db_pool is intended to be database-agnostic, compatible with any DB-API 2.0 database module.

A ConnectionPool object represents a pool of connections open to a particular database. The arguments to the constructor include the database-software-specific module, the host name, and the credentials required for authentication. After construction, the ConnectionPool object decides when to create and sever connections with the target database.
