I am not exactly sure what you mean by the term "registers". I have heard of databases being described as fields (columns) and tuples (rows). Registers is only something I have heard in association with CPU architecture....
If you mean "can MySQL handle a dataset of 20 million rows?" the answer is "yes, with ease". That assumes you have enough physical space (memory or disk) to store it all. There are installations running with several tables that each have hundreds of millions of rows of data. Check the archives for some representative numbers (this is not an uncommon question).
