CAP theorem
The CAP theorem states that a distributed data store can provide only two of three guarantees at the same time. Those guarantees are consistency, availability, and partition tolerance. Because real networks inevitably drop messages, partition tolerance is not really optional. So the practical choice is between staying consistent and staying available when the network splits.
Consistency, availability, aur partition tolerance.

Who it's for
For anyone who learns better by listening.

“The chapter I'd been avoiding, explained in Hinglish on the bus.”
Student
“Long articles, read to me while I cook.”
Reader
“The 40-page report: brief first, details after.”
