MySQL version 3.22 has a maximum table size limit of 4GB (4 gigabytes). mySQL version 3.23 uses the MySQL table format, and this limit is a massive 800TB (2^63 bytes)! What is the concept of 800TB? The actual comparison of Yahoo's huge search engine database is still not (by no means) more than 30TB, so let's say 30TB, which means that the size of a single MySQL table volume is about 26.7 times the size of the yahoo search engine database!
