I feel like 1 - 2 years ago I was reading a slew of blog posts with the title "Why We Chose MongoDB." Now it seems like all of the blog posts are some sort of "We Just Finished Migrating off of MongoDB, Here's Why."
I know nothing about MongoDB and have never tried it. But the message seems pretty clear.
- bunderbunder 14y agoIt's just the standard Internet hype cycle. I'm guessing within the next year we're going to see a similar backlash against Hadoop as people who rush to it begin to discover that map/reduce isn't necessarily the best distributed processing model for their needs. This despite Hadoop continuing to be the effective (non-silver) bullet it's always been.
- gfodor 14y agoMeh, Hadoop is much older than MongoDB, is an offline system, and doesn't destroy your data. There is also not much in the way of alternatives. I'm skeptical we will see many "we're switching off of Hadoop" posts anytime soon. That said, there is an growing undercurrent in the Clojure community to roll your own map reduce system instead of using Hadoop.
- bunderbunder 14y agoThere's quite a bit in the way of alternatives. Sector/Sphere, Xgrid, and PVM come to mind. Sector/Sphere is perhaps the most direct alternative since it comes with its own distributed filesystem, but if you don't need a full-fledged DFS then the others are worth looking at too. The main thing that really distinguishes Hadoop is that it's built to only do one kind of distributed processing. In exchange for asking you to don that straitjacket it offers ease of use. However, if your problem isn't naturally a map/reduce problem, or if your main performance bottleneck isn't disk I/O, then the alternatives become a lot more attractive.
- ax 14y agoThe message is, just like every technology, there's an initial period where a vocal minority loves it and tries to use it for everything. Then, there's a backlash where a vocal minority hates it and thinks anyone who uses it is clearly an idiot. All the while, the silent majority go on getting work done. It's been this way for as long as I can remember.
- nchuhoai 14y agoLove it. I think Node is the hot shit right now, and Rails is starting to get into the hate-period. It's really just hipsters and music. We are all really just hipsters.
- macspoofing 14y ago>I think Node is the hot shit right now, and Rails is starting to get into the hate-period. I think you're about two years behind. Node is starting its hate-period. Rails got it a year or two ago.
- datasage 14y agoThere are a lot of people still switching to MongoDB for various reasons, but its no longer the cool kid on the block and thus not a lot of people are going to brag about switching to it. I think a lot of people switched to it because it was cool, and maybe assumed that it could solve any application data storage problem and are now finding out that it may not have been a great choice for them. I don't think its appropriate to take away from this that MongoDB and/or other document stores are bad. Instead, I think its important to understand how they work and decide how well it applies to your use case. It's not going to work well for all applications.
