No SQL = Not Only SQL

Good article. I come from a background where I had to deal with these sorts of scale well before the modern NoSQL offerings existed. Any mission critical system at massive scale, like the ones discussed here, need to have rock solid monitoring and alerting and the smallest of design decisions can have huge echoes when things scale up regardless of your tech stack. Sure there is work to be done when using MongoDB but its a heck of a lot better than the alternative!

Any of these problems really MongoDB or NoSQL specific? All types of databases suffer from these kinds of limits.

Good article, I like the real cases. I’d argue though that if you have more than a few million records or incur lots of traffic, take any data storage of any kind and you will need someone who knows what they’re doing.

Not Oracle, DB2, MSSQL, MySql, cassandra, HBase or BerklyDB will run well without someone knowing the system and doing the work to make it run well and innovate for the use case at hand. Find one website about Oracle that doesn’t sell you Oracle professional support – and this is not because it’s a bad product, but not one is a golden hammer.

Finding the right tool for your use case makes can make a huge difference, but it will only increase/decrease the amount of your own creation required to make the system work for you.

Actually I think it’s pretty damn amazing we’re running these apps practically all from RAM. Makes me wonder what sort of innovation’s gonna be needed to keep up with the growing demand.

MongoDB – NoSQl DB because it does not support SQL, may be?

@Derrick Harris: Nice article about real-world experiences, thanks. I had no difficulty distinguishing between NoSQL and MongoDB references in the article.

Yeah, I didn’t mention any others, but I think the same (or similar) lessons apply equally elsewhere — Cassandra, CouchDB, etc. I just focused on Mongo because of the event, but perhaps should have pointed to coverage of other NoSQL projects (which I do below). Users tend to be really happy with their choices, but the non-commercial versions, in particular, do take some work to optimize for any given workload. Just like any other open source product.

Did you mean to reply to me? I didn’t write this article… but you’re absolutely right. The article title is way off…

Is Mongo the on NoSQL Database? I didn’t see you mention any others…
