2 weeks ago I came across a post by Facebook which was written in 2022 on how they improved their cache consistency to 99.99999999 percent (10 nines) that means less than 1 out of 10 billion cache writes are inconsistent in meta after 5 minutes. I have tried to write a detailed blog on it and also tried to reproduce an actual bug which they solved during this process. I have implemented the code in python on my github https://lnkd.in/g3KmMat7. This blog was originally written by Lu Pan and I have tried to write it in my words and what I understood out of it.
