Viber, one of the largest over the top messaging apps, recently shared their conversion from Mongo to Couchbase. They ended up requiring less than half of the original servers, and better performance. If you want to see a video of their engineer telling the story, it's available here: http://www.couchbase.com/presentations/couchbase-tlv-2014-co...

Like always: "Use the right tool for the job". I did not think that this was MongoDB(10gen)s fault, they (viber) choose the wrong database type for their needs.

Earlier quoted context omitted.

Knowing some of the FC people first hand, MongoDB did actually serve them fairly well for a substantial amount of time. Until they started hitting max limits, it didn't really make sense to move to c . Going straight to C or something like it would have been almost cargo-cultish ( eg If we build industrial strength, we will get industrial levels of traffic ).

Exactly. Can you imagine all of the Java/C developers telling Ruby developers that they are idiots and don't know anything about programming ? Simply because they choose a technology that is designed for developer productivity at the expense of scalability. Because that what seems to happen for every database discussion.

No, because Ruby also runs on the JVM/.NET and has native code compilers available.

When I read posts like this all but confirming MongoDB isn't the great product 10Gen make it out to be, I wonder how the heck MongoDB are still even relevant and then I remind myself of the fact that 10Gen have one of the best marketing and sales teams in the game at the moment. While MongoDB has improved greatly over previous versions, I can't help but feel if 10Gen put as much effort into improving their product as…

Just as a historical note, I meant to type C Star ( C\* ) but HN's formatting changed c\* into C. C\* is shorthand for Cassandra.

> 10Gen have one of the best marketing and sales teams in the game at the moment. No doubt. I have 2 MongoDB mugs even though I vowed to never touch a product produced by them again (it was, after the whole -- we'll throw your data write requests over the wall and pray fiasco).

I have one from an event they did here. What's telling is that I'm in Houston - far outside the SF/SV magic bubble.

I also have one and I'm from Ohio :|

Mongodb has marketed the database as a general purpose one when in reality it doesn't even come close to one. And the case is the same for all other NoSQL systems. No More general purpose database? The developers at http://www.amisalabs.com are tackling today's database problems.

you know they have been tackling without a release for many months now

Yet another shining example of throwing money and time away to work within AWS constraints when bare metal and openstack (1) would have solved it cheaper (2) and arguably faster.

1 (if you insist on cloud provisioning instances, even though it makes little sense if the resources are as strictly dedicated as they are in this case)

2 (VASTLY, over time -- these guys are pissing money away at AWS and I hope their investors know it)

As someone who works extensively in "Enterprise IT" it's the unifying factor in most successful middleware companies. I'm working with a CMS that has barely updated a single core feature in almost 10 years, consistently releases with glaring bugs and rakes in millions in license fees. How? Sales team always show a polished demo and don't give out dev licenses for evaluation.

Same here.

Author here, sorry about that. It's not supposed to display on engineering posts but something must have changed/been broken recently. We know you guys aren't interested in marketing content. Again, sorry about that and thanks for bringing it up.

I read the article on my iPhone and found the hovering "top" button in the lower right both unnecessary and very obtrusive.

iOS has a standard way to jump to the top (tap top of screen), there is no need to interfere with the content.

We understand that AWS comes at a premium, however we find the opportunity cost of losing the agility we have on AWS at this stage of our organization more expensive than the delta in cost between moving on to our own hardware and AWS.

Our organization is acutely aware of our costs and still strives to minimize them. Our move to Cassandra saved 79% over continuing to run our reserved SSD nodes & backup replica.
