The Mysql optimization table prompts the table is already the resolve method of the up to date _mysql

When the database is optimized using phpMyAdmin in the background, it is displayed as "Table is already up to date".

Many people may be worried about this, because the default optimization table prompts "status OK" as follows:

Table Op Msg_type Msg_text
Commentmeta Optimize status OK
Comments Optimize Status OK
Term_taxonomy Optimize status OK
Usermeta Optimize status OK
Users optimize Status OK

In fact, there is no need for questions and concerns, literally, "table is already up to date" that is "datasheet is already current"

That is, the table has been optimized and no further optimizations are needed.

In general, there are several situations where this can be prompted:

1, not long ago repaired

2, no data or long-term use of the table
