Amazon reveals its secret key-data overlords from the planet Cloud

October 3rd, 2007

Only the barest of glances at Dynamo so far, and by far the most interesting pieces are going to be how they do the scalable high availability, and of course we’re talking about “Werner Vogels Scalability(tm)“, but I was immediately struck, [as Sam was](http://intertwingly.net/blog/2007/10/03/Key-Data ), by the this pattern key+data we’re seeing:

  • memcached (everybody is using it)
  • CouchDb (everybody is talking about it)
  • Berkely DB (Bloglines and Yahoo to name just two, plus Google, thanks Steve)
  • Facebook Data Store API
  • and now Dynamo.

Meanwhile Assaf argues well that not all keys are created equal

    Are you sure you’re not thinking of CouchDB (which has the key+value pattern you and Sam are referring to)? I haven’t seen anyone mention CloudDB since April.

    Joe, yes, thanks, fixed. My excitement got away from me.

    Memcached/Dynamo is hash(key)=>data. CouchDB is id=>data, with the addition that data=>key=>id. I’m not arguing one is better than the other, just that the difference is not subtle.
