hi,
I'm using innodb engine. There are more and more rows in my table
recently, and
I've planned to extend the structure.
Assume I have testdb, the database, and testTab, the table, in ONE mysql.
There are two ways:
* extend via table, that is,
testTab -----> testTab_1
-----> testTab_2
-----> testTab_3
* extend via database, that is,
testdb/testTab ------> testdb_1/testTab
------> testdb_2/testTab
------> testdb_3/testTab
After the extend operation, all tables & databses will be at the SAME
mysql firstly,
then migration to newly-add other mysql on demand.
Which way is better?
Thank you
