I’ve read an article about Innodb performance optimization an in that post the author was repeatedly mentioning someting named a “battery back up cache”. It is not clear for me what he was talking about and google did not help either. My guess is that this is some kind of backup storage in case there is a power outage. Am I right?

How does Google store its PageRank matrix?

I’m curious to know how Google stores the matrix that’s used in the PageRank algorithm; and am looking for a data-structure for storing a very-large (not fitting in memory of any one computer) sparse matrix, and efficiently (not sure what that means yet) performing operations on it.
