Create MySQL InnoDB dumps with bulk inserts?

Question

I need to speed up the import of a sql.gz file into mysql. I have turned off foreign key checking and followed this page .

My question is:

Is there a way to make the export file (the sql.gz) from mysqldump user multi-insert statements like this:

INSERT INTO yourtable 
VALUES (1,2), (5,5), ...;

so that the bulk loading process will be much faster?

Answer 1

mysqldump does this by default. There are many other options (such as use REPLACE or INSERT IGNORE as opposed to the default INSERT command) run mysqldump --help to see the list.

You might try LOAD DATA INFILE to see if that is faster. That will read the data from a tab delimited text file without any INSERT commands. You would use SELECT ... INTO OUTFILE 'file_name' as one way to create this data file.
