How to select a pool based on client's hostname?

What if I forget the datagroup idea and just use text matching like this...

You could use a switch statement to evaluate multiple strings that aren't in a data group:

switch -glob -- [string tolower $ptr] {
   "*wtsappprod" {
      pool prod_pool
   }
   "*wtsapp" {
      pool preprod_pool
   }
}

I should have the caching -ptr example ready in a little while.
