How do you make MySQL insert faster?

How do you make MySQL insert faster?

To optimize insert speed, combine many small operations into a single large operation. Ideally, you make a single connection, send the data for many new rows at once, and delay all index updates and consistency checking until the very end.

How can I make my insert faster?

You can use the following methods to speed up inserts: If you are inserting many rows from the same client at the same time, use INSERT statements with multiple VALUES lists to insert several rows at a time. This is considerably faster (many times faster in some cases) than using separate single-row INSERT statements.

How increase SQL insert performance?

1. Use partition switch to move ‘in’ the data. This is, by far, the best solution.
2. Make sure the INSERT is minimally logged. Read Operations That Can Be Minimally Logged and Prerequisites for Minimal Logging.
3. Make sure your IO subsystem is capable of driving a fast load. Read Introducing SSDs.

Does MySQL support bulk insert?

Using Bulk Insert Statement in MySQL. The INSERT statement in MySQL also supports the use of VALUES syntax to insert multiple rows as a bulk insert statement. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.

How to improve insert performance on a very large mysql table?

This is usually 20 times faster than using INSERT statements. Take advantage of the fact that columns have default values. Insert values explicitly only when the value to be inserted differs from the default. This reduces the parsing that MySQL must do and improves the insert speed.

What’s the best insert speed for MySQL database?

If you really want high inserts, use the BLACK HOLE table type with replication. It’s essentially writing to a log file that eventually gets replicated to a regular database table. You could even query the slave without affecting insert speeds. Firebird can easily handle 5000 Insert/sec if table doesn’t have indices.

Which is the best insert file for MySQL?

As expected, LOAD DATA INFILE is the preferred solution when looking for raw performance on a single connection. It requires you to prepare a properly formatted file, so if you have to generate this file first, and/or transfer it to the database server, be sure to take that into account when measuring insert speed.

What are the benefits of extended inserts in MySQL?

The benefit of extended inserts is higher over the network, because sequential insert speed becomes a function of your latency: max sequential inserts per second ~= 1000 / ping in milliseconds The higher the latency between the client and the server, the more you’ll benefit from using extended inserts.
