from the ask-hn dept.

I'm building a Q&A site. Would like to use a distributed DB for data store.Requirements:1) Elastic: add nodes and scale out automatically2) HA: automatically & transparently provides replication & failover3) Locality: I'd like to group all answers to the same question together and put them in the same shard. That way when retrieving answers to a question I won't need to query all...

Re:Ask HN: What is your preferred Python stack for high traffic webser... on Monday August 22, 2011 @10:20AM (#2912520)

gevent has utilities to turn Python blocking calls into non-blocking ones.

In your case you could switch to a pure Python MySQL driver and gevent will turn all your mySQL calls into async.

Actually there're also gevent non-blocking MySQL drivers that are written in C.

That's what friendster thought too.

Friendster became very popular but couldn't handle the scalability part and ended up dying a slow and painful death...
