How many database does Facebook have?
I'm curious, how many databases does Facebook have?
Facebook has a massive infrastructure, with thousands of servers and multiple data centers across the world. But when it comes to the number of databases they have, it's difficult to give a specific answer. Facebook uses various database technologies for different purposes, such as MySQL, HBase, Cassandra, and more. Plus, they have internal tools and systems to manage data storage and processing. So the number of databases isn't a straightforward metric to measure. Does that answer your question, or is there anything else I can help you with?
