Block size in MySQL

Hi everybody
I have heard in Oracle, we can change the block size of data (which can be so useful in OLTP databases, to reduce the block size). I want to know if there is any similar facility in MySQL as well. Is it possible to change block size of data in MySQL? If yes, please give me some resources to find about it.
Cheers!
