Links to performance numbers posted wrt various NoSQL solutions:
A top 20 global website announced they have migrated from MySQL to Redis. There will be a keynote and everything. It doesn't say how big the Redis Cluster is, but they serve 100M pages / day, and clock 300k Redis queries / second.
Btw, they mention that MySQL remains as the master data store from which the Redis indexes are generated.
(The reason I don't mention the name of this Redis user is simply I feat my mom is sometimes reading my blog...)
This is an oldie, but already 2 years ago DeNA posted a benchmark doing 750k MySQL queries / second on only a single server. This was with HandlerSocket, the first widely used NoSQL API for InnoDB based MySQL databases.
Last week MySQL Cluster team announced a new version. (congratulations, fellows!) The hardware in this benchmark is quite beefy: 8 modern servers with Infiniband as the interconnect. Even so the results, again using the NDB NoSQL API, are impressive: 1 billion queries per minute, or 17 million per second.
It should be mentioned the above is not an apples to oranges comparison. The Redis numbers are from a production installation and not a benchmark. Obviously you wouldn't want to max out your performance in production. Quite the contrary: for HA purposes you want to make sure to run at most at 50% your capacity. So if we take this 50% limit into account, then MySQL Cluster can only do a measly 8 million queries per second :-)
PS: I've seen the Austin Powers movies, twice, yet I can't understand the joke in Jonas blog. This can only mean one thing: I have to watch them again now!
