HyperDB is a very advanced database class that replaces a few of the WordPress built-in database functions. The main differences are: 
* HyperDB can be connect to an arbitrary number of database servers, 
* HyperDB inspects each query to determine the appropriate database.
It supports:
<ul>
<li>Read and write servers (replication)</li>
<li>Configurable priority for reading and writing</li>
<li>Local and remote datacenters</li>
<li>Private and public networks</li>
<li>Different tables on different databases/hosts</li>
<li>Smart post-write master reads</li>
<li>Failover for downed host</li>
<li>Advanced statistics for profiling</li>
<li>WordPress Multisite</li>
</ul>
It is based on the code currently used in production on WordPress.com with many MySQL servers spanning multiple datacenters.

HyperDB is a amazing feature.


	You want to make two websites share a (user) table? OK!
	You want to make a website use two databases so we can create a development workflow to "deploy" content in the same time we persist production data? OK!
	And so on...


Of course is unnecessary to talk about how it can help in scaling... Just perfect.


It's just amazing!

This plugin works very well with AWS RDS and read replica.

Works very well with RDS and read Replica

Maybe this plugin is not so popular because many WordPress users are just not technical users, but I truly glad the plugin is here, and hopefully the WordPress team still always have a time to maintenance this :)

Kudos! 

A hidden gem
