MySQL partition Table partition online modify partition field company online use partition, there is a table partition field error, need to be rebuilt, it turns out that there is no way to directly execute an SQL statement like modifying the primary key field or modifying the index field. Instead, you need to create a temporary table with a down time. So I carefully read the document and studied the details of partition. When your company is online, the business is off-peak at.
