Question

I have data containing about 30 000 records. And I need to insert this data into MySQL table. I group this data in packages by 1000 and create multiple inserts like this:

INSERT INTO `table_name` VALUES (data1), (data2), ..., (data1000);

How can I optimize performance of this inserting? Can I insert more than 1000 records per time? Each row contains data with size about 1KB. Thanks.

Answer 1

You need to check mysql server configurations and specifically check buffer size etc.

You can remove indexes from the table, if any, to make it faster. Create the indexes onces data is in.

Look here, you should get all you need.

One insert statement with multiple values, it says, is much faster than multiple insert statements.
