Importing data into an Amazon RDS for MariaDB DB instance

You can use several different techniques to import data into an RDS for MariaDB DB instance. The best approach depends on a number of factors:

  • Source of the data

  • Amount of data

  • One-time import or ongoing

  • Amount of downtime

If you are also migrating an application with the data, the amount of downtime is important to consider.

The following table lists techniques to importing data into an RDS for MariaDB DB instance:

Note

Amazon RDS only supports importing from Amazon S3 into RDS for MySQL DB instances. Importing backups created with mariadb-backup into RDS for MariaDB isn't currently supported.

Source Amount of data One time or ongoing Application downtime Technique More information

Existing MariaDB database on premises or on Amazon EC2

Any

Ongoing

Minimal

Configure replication with an existing MariaDB database as the replication source.

You can configure replication into a MariaDB DB instance using MariaDB global transaction identifiers (GTIDs) when the external instance is MariaDB version 10.0.24 or higher, or using binary log coordinates for MariaDB instances on earlier versions than 10.0.24. MariaDB GTIDs are implemented differently than MySQL GTIDs, which aren't supported by Amazon RDS.

Importing data to an Amazon RDS for MariaDB DB instance with reduced downtime

Any existing database

Any

One time or ongoing

Minimal

Use Amazon Database Migration Service to migrate the database with minimal downtime and, for many database DB engines, continue ongoing replication.

Existing MariaDB DB instance

Any

One time or ongoing

Minimal

Create a read replica for ongoing replication. Promote the read replica for one-time creation of a new DB instance.

Copy the data directly to your MariaDB DB instance using a command-line utility.

Create flat files and import them using MariaDB LOAD DATA LOCAL INFILE statements.

Importing data from any source to an Amazon RDS for MariaDB DB instance
Note

The mysql system database contains authentication and authorization information required to log in to your DB instance and access your data. Dropping, altering, renaming, or truncating tables, data, or other contents of the mysql database in your DB instance can result in errors and might render the DB instance and your data inaccessible. If this occurs, you can restore the DB instance from a snapshot using the Amazon CLI restore-db-instance-from-db-snapshot command. You can recover the DB instance using restore-db-instance-to-point-in-time command.
