[seam-dev] Friendly documentation

[Sebastian Hennebrueder]

Hello,

in chapter 19 (caching) of the seam documentation, there is the 
following paragraph. In my opinion, it is not at all polite as we call 
them silly, use expressions like 'will try to tell you' and so on.

Dealing with other people in that way does not express better technology 
or better knowledge. I would interprete it as being snobbish, subjectiv 
and find that it is not very much convincing. Though I know that the 
core argument is in fact correct.

May be it is just me being to sensible, but what is your opinion on this.

Best Regards

Sebastian Hennebrueder

In almost all enterprise applications, the database is the primary 
bottleneck, and the least scalable tier of the
runtime environment. People from a PHP/Ruby environment will try to tell 
you that so-called "shared nothing"
architectures scale well. While that may be literally true, I don't know 
of many interesting multi-user applica-
tions which can be implemented with no sharing of resources between 
different nodes of the cluster. What these
silly people are really thinking of is a "share nothing except for the 
database" architecture. ....

alternative formulation:
In almost all enterprise applications, the database is the primary 
bottleneck, and the least scalable tier of the runtime environment. 
People from a PHP/Ruby environment state that their lightweigth 
architecture - which is not sharing resources - scales well. We do not 
agree here. A PHP/Ruby will share the database which is in large scale 
application normally already the bottleneck. Lightweight can be fast in 
smaller applications but is not scalable.

This chapter explains how Seam uses caching to provide a architecture 
which is fast and scalable at the same time.
