Installing and configuring RocksDB as a storage engine in MariaDB involves several steps, as RocksDB is an alternative to the default InnoDB engine and offers performance benefits for certain workloads. Here’s how to do it:

Step 1: Install MariaDB with RocksDB Support

  1. Check for RocksDB Support: Ensure that your MariaDB version supports RocksDB. MariaDB 10.2 and later versions typically include RocksDB.
  2. Install MariaDB: If not already installed, install MariaDB from the official repositories or MariaDB's website. For Linux distributions, use the package manager:

Step 2: Enable the RocksDB Storage Engine

  1. Configure MariaDB: Edit the MariaDB configuration file (/etc/my.cnf or /etc/mysql/mariadb.conf.d/50-server.cnf), and add the following lines under the [mysqld] section to enable RocksDB:
  2. Restart MariaDB: After modifying the configuration, restart the MariaDB server to apply the changes:

Step 3: Verify RocksDB Installation

  • Check Storage Engines: Verify that RocksDB is installed and available by logging into the MariaDB shell and running: Look for RocksDB in the output.

Step 4: Create and Use a RocksDB Table

  1. Create a RocksDB Table: To create a table using RocksDB, specify the ENGINE=RocksDB option:
  2. Use the Table: You can now use this table as you would with any other MariaDB table. The data will be stored using the RocksDB engine.

Step 5: Configure RocksDB Specific Settings (Optional)

  • RocksDB offers various configuration options that you can set in the MariaDB configuration file to optimize performance according to your workload. Some common settings include:
  • Refer to the RocksDB and MariaDB documentation for detailed descriptions of these settings and others.

Step 6: Monitor and Optimize

  • Monitor Performance: Regularly monitor the performance of your MariaDB server. Tools like mytop, mariadb-top, and various monitoring solutions can help.
  • Optimization: Depending on your workload, you might need to adjust RocksDB settings over time for optimal performance.


RocksDB can be a powerful storage engine for MariaDB, especially for workloads requiring high performance and efficiency in reading and writing key-value data. Ensure that your MariaDB version supports RocksDB, enable it in the server configuration, and carefully tune RocksDB settings to match your specific workload requirements. Regular monitoring and optimization are key to getting the most out of this storage engine.
