Announcement: Amazon Relational Database Service (Amazon RDS) for MariaDB 10.2 End-of-Life date is October 15, 2022


Amazon RDS is starting the end of life (EOL) process for MariaDB major engine version 10.2. We are doing this because the MariaDB community is planning to discontinue support for MariaDB 10.2 on May 23, 2022 [1].

Amazon RDS for MariaDB 10.2 will reach end of life on October 15, 2022 00:00:01 AM UTC. While you will be able to run your Amazon RDS for MariaDB 10.2 databases between community MariaDB 10.2 EOL (May 23, 2022) and Amazon RDS for MariaDB 10.2 EOL (October 15, 2022), these databases will not receive any security patches during this extended availability period. We strongly recommend that you proactively upgrade your databases to major version 10.3 or greater before community EOL on May 23, 2022. MariaDB 10.3 offers improved Oracle compatibility, support for querying historical states of the database, features that increase flexibility for developers and DBAs, and improved manageability [2]. Our most recent release, Amazon RDS for MariaDB 10.6, introduces multiple MariaDB features to enhance the performance, scalability, reliability and manageability of your workloads, including MyRocks storage engine, IAM integration, one-step multi-major upgrade, delayed replication, improved Oracle PL/SQL compatibility and Atomic DDL [3]. If you choose to upgrade to MariaDB 10.6, you will be able to upgrade your MariaDB 10.2 instances seamlessly to Amazon RDS for MariaDB 10.6 in a single step, thus reducing downtime substantially. Both versions, MariaDB 10.3 and 10.6, contain numerous fixes to various software bugs in earlier versions of the database.

If you do not upgrade your databases before October 15, 2022, Amazon RDS will upgrade your MariaDB 10.2 databases to 10.3 during a scheduled maintenance window between October 15, 2022 00:00:01 UTC and November 15, 2022 00:00:01 UTC. On January 15, 2023 00:00:01 AM UTC, any Amazon RDS for MariaDB 10.2 databases that remain will be upgraded to version 10.3 regardless of whether the instances are in a maintenance window or not.

You can initiate an upgrade of your database instance to a newer major version of MariaDB — either immediately or during your next maintenance window — using the AWS Management Console or the AWS Command Line Interface (CLI). The upgrade process will shut down the database instance, perform the upgrade, and restart the database instance. The database instance may be restarted multiple times during the upgrade process. While major version upgrades typically complete within the standard maintenance window, the duration of the upgrade depends on the number of objects within the database. To avoid any unplanned unavailability outside your maintenance window, we recommend that you first take a snapshot of your database and test the upgrade to get an estimate of the upgrade duration. If you are operating an Amazon RDS for MariaDB 10.2 database on one of the retired instance types (t1, m1, m2), you will need to migrate to a newer instance type before upgrading the engine major version. To learn more about upgrading MariaDB major versions in Amazon RDS, review the Upgrading Database Versions page [4].

We want to make you aware of the following additional milestones associated with upgrading databases that are reaching EOL.

**Now through October 15, 2022 00:00:01 AM UTC **- You can initiate upgrades of Amazon RDS for MariaDB 10.2 instances to MariaDB 10.3 or 10.6 at any time.

July 15, 2022 00:00:01 AM UTC – After this date and time, you cannot create new Amazon RDS instances with MariaDB 10.2 from either the AWS Console or the CLI. You can continue to restore your MariaDB 10.2 snapshots as well as create read replicas with version 10.2 until the October 15, 2022 end of support date.

October 15, 2022 00:00:01 AM UTC - Amazon RDS will automatically upgrade MariaDB 10.2 instances to version 10.3 within the earliest scheduled maintenance window that follows. After this date and time, any restoration of Amazon RDS for MariaDB 10.2 database snapshots will result in an automatic upgrade of the restored database to a still supported version at the time.

January 15, 2023 00:00:01 AM UTC - Amazon RDS will automatically upgrade any remaining MariaDB 10.2 instances to version 10.3 whether or not they are in a maintenance window.
