Exporting Data From MemSQL

This topic describes how to export data from MemSQL databases using mysqldump, which you can use because MemSQL supports the same query-level inputs and outputs as MySQL. mysqldump creates a .sql file containing the queries necessary to recreate a database. You can run the output of mysqldump against an instance of MemSQL or MySQL, so you can use this strategy to move data between the two.

Backing up a Single Database

$ mysqldump -h 127.0.0.1 -u root -P 3306 foo > foo.sql

If you have a database named “foo”, you can create a backup with the following command:

Backing up All Databases

If you want to back up every database in an instance of MemSQL, use the following command:

$ mysqldump -h 127.0.0.1 -u root -P 3306 --all-databases > full_backup.sql
Info

Mysqldump uses LOCK TABLES to help ensure that it reads a consistent view of the database as it queries across tables.

This means you cannot run write queries against the database while the backup is being performed.
