MariaDB is a popular open-source, community-driven relational database management system (RDBMS) and serves as an excellent alternative to MySQL. At its core, MariaDB employs Structured Query Language (SQL) to manage, create, and interact with databases. 

It utilizes a schema-based structure where data is organized into tables, each containing rows representing individual records and columns representing attributes. You can effortlessly create and maintain relationships between these tables using primary and foreign keys, ensuring your data stays interconnected.

What Is Amazon Redshift?

Limitations of using AWS Data Migration Service

While you can migrate your data from MariaDB to Amazon Redshift using AWS Data Migration Service, it's important to consider certain limitations associated with the process:

  • Allocated Storage Limit: AWS DMS Serverless provides a statically allocated storage of 100GB for a replication. If your migration requires more storage, then you'll need to partition your workload into separate serverless replications. Additionally, you might need to manage data synchronization and consistency across replications, which can be complex.
  • Migration of Temporal Data Tables Unavailable: MariaDB's temporal data tables, also known as system-versioned tables, are not supported for migration using AWS DMS. These tables allow you to keep a history of changes to data over time, and their migration to Amazon Redshift might require alternative approaches.
  • Views Migration Not Supported: AWS DMS does not support migrating views from a MariaDB source database to a target database. Views are virtual tables that represent the result of a database query. If your MariaDB database utilizes views extensively, you must consider alternative strategies for migrating your data target Redshift database.

The Takeaway

Moving data from MariaDB to Redshift might seem complicated. But this guide has made it easier by exploring two methods. There’s the manual method of using AWS Data Migration Service (DMS) to connect MariaDB and Redshift.
