MySQL what is the maximum size of a database?

Question

I have looked all over the MySQL website and found no definitive answers.

1. Is the size of the database determined by the operating system or is there 4GB limit

Answer 1

default mysql is 256 TB for myd file with 6 byte pointer size. i know this is ridiculous answer, but that is what you wanted to know. in real life all depends on the queries, indexes, column count, row count, etc.. i guess.
