Whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

TwittEr uses Ruby On Rails.

[Alex Payne] complained about Scalabil Ity problems, esp associated with Rails supporting connection to only a single Data Base.

DHH replies

then points to a sudden patch by [Nic Williams] to support multi dbs. In the comments, [Blaine Cook] provides more details of the actual TwittEr situation: For the record, Twitter is not currently database bound, and won't be for at least a month (unless our growth rate increases), something that David was aware of when we spoke to him a couple of weeks ago... The current largest bottleneck we have without a clear solution (other than hand-optimization) is the cost of rendering templates (Template System)... I hope that my talk on Sunday at [SDForum] will clarify our experience with Rails at Twitter, and offer insights to others. Here's Blaine's own blog post.

Another perspective on talking to multiple databases.

[Jens Alfke] wonders whether a Data Base is even needed, vs just using the File System.
