Can someone at Facebook verify if the answer on Quora is accurate/mostly accurate?

It's basically accurate. Also, there are upvotes from notable employees at Facebook like Andrew Bosworth

It seems to be pretty consistent with the engineering blog http://m.facebook.com/Engineering?_rdr

Great to see this in one place. I would love to know more about the more internal facing systems (code deployment, test frameworks, failover systems...).

I like the anon comment that they should not re-invent the wheel so much. That gave me a chuckle, I'll just use my off the shelf distributed web app deployment software that runs on thousands of machines ... oh snap!

What's facebook take on memcached? Are they happy with it?

orijing3• 15 years ago

It worked well in the past. They made significant improvements to it.

However, it's not as well-suited for multi-datacenter usage. For example, they needed another replication layer. I think they're working on a current system that will replace memcached, and it seems to be causing some consistency problems...

Do you have any additional details about this possible memcached replacement?

shin_lao2• 15 years ago

The new system is causing consistency problems or memcached?
