Scalability problems are kind of problems many developers and entrepreneurs would like to have. I your already dealing with such problems, you had to notice important feature missing in Zend_Db – support of database replication.

Database replication is an option that allows the content of one database to be replicated to another database or databases, providing a mechanism to scale out the database. Scaling out the database allows more activities to be processed and more users to access the database by running multiple copies of the databases on different machines.

In a recent post on his blog Federico Cargnuletti presents his implementation of Zend_Db replication adapter. It supports single-master and multi-master architectures, as well as connection status caching. Read his post and code before implementing your own replication adapter – you might have it already done.
