Winning a benchmark against MongoDB on a non-trivial workload is a little bit like winning the special olympics. I'd be more curious to see how Clustrix performs against Cassandra, Riak or HBase in their respective domains. Those seem to be the more serious contenders when it comes to "Big Data".

I chose Mongo because it gets a lot more attention on HN than any other database. I don't remember the last time I saw a post on Cassandra on here...

  I think I see Redis more than Mongo.

  I get the impression that Mongo is simple to use and simple to program for; Cassandra is quite good, but also more complicated.

Would you care to elaborate? Seriously, do you have any pointers or benchmarks for a Mongo vs Cassandra vs X comparison that isn't purely anecdotal, and which takes the relative strengths of each into account in a robust way? A lot of blog posts with performance numbers seem anecdotal or loaded towards one option over the other. I'm excited by some of the underlying technology in Mongo and its ilk (gossiping protocols, etc.), but there's no doubt that they require different programming techniques than traditional RDBMS. Bit like apples and oranges, isn't it? EDIT: I noticed you changed RDBMS to "big data". I'm still curious if you have any pointers to fair benchmarks though.

  Well, don't trust a benchmark that you haven't faked yourself they say. I was just trying to point out that MongoDB is too easy a target here. The problems it has under high load are fairly well-known, at least to anyone who tried to benchmark it outside of their MacBooks. Just bulk-load a couple million records and watch it tip over if you don't believe me - I'm not making it up and neither is Sergei. However if Clustrix wants to impress with benchmarks then they should pick an equal opponent. MongoDB is not exactly relevant for companies that consider the calibre (and cost!) of Clustrix.

    I am a Mongo fan in some respects, but I agree that every benchmarking I do with any significant data involves the painfully slow bulk writes to get it started -- not a good first impression. Can some Mongo people help explain this?

i guess rdbms will never show "older tweets are temporary unavailable". because we don't need that, its our special domain! :) //ps. i am a huge nosql fan dont downvote! :)
