To run script use perl message_data.cfg user_credentials.cfg if your database key primary has type that should be extended the script will notify you for example: if we have type int ("int" => 2147483647) for primary key and it is auto increment and we will have large table size for exaple 2007483647 script alert us that we should overload table Script gives this output: max size of int unsigned = 4294967295 column contains 3980644270 rows Difference between size of int unsigned - table rows =314323025
percent size captured (int unsigned/rows)0.926815967756979 Overload it!!!!!=====================================================
