Mysql partition error, and how to optimize the novel subscription table?
CREATE TABLE `yy_subscribe2` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,

);
mysql reports this error when creating a partition: For RANGE partitions each partition must be defined.
what is the reason.
In addition, this is a chapter subscription form for the novel. Used to record which chapter of which book the user has subscribed to. There are currently 3000W pieces of data. Indexing has already been done. Will the planned use of partitions have an effect on subsequent data growth? Or use other methods without partitioning?
