Home -> Community -> Usenet -> c.d.o.tools -> Re: Using Index-Organized Table (IOT)
The administrative overhead with IOT's occurs in connection with the
creation parameters pcttreshold and overflow (see Oracle documentation). In
many cases, that may
not be a problem.
What may be worse is the fact that IOT's cannot be partitioned or replicated (see Oracle documentation).
With these potential problems in mind, only use IOT's when you have a good reason.
If it can help make your application faster by saving a sort, that may be a good reason. It's a case-specific trade-off. Just remember that applications change but tables remain ( mostly ;-) )
