MariaDB features and specs

• Open Source
  MariaDB is fully open-source, which means it is free to use, modify, and distribute. There are no licensing fees, making it a cost-effective solution for businesses of all sizes.
• Compatibility with MySQL
  MariaDB is designed as a drop-in replacement for MySQL. It offers extensive compatibility, making it easy to switch from MySQL without needing to make significant changes to the codebase.
• Performance
  MariaDB often offers better performance and scalability compared to other relational databases. It includes enhancements in query optimization and indexing, which can lead to faster data retrieval.
• Advanced Features
  MariaDB includes advanced features such as the Aria storage engine, dynamic columns, and thread pooling. These features provide more flexibility and control over database management and optimization.
• Active Community
  Being open-source, MariaDB benefits from a robust and active community of developers and users who contribute to its development and provide support through forums and other channels.
• Security
  MariaDB is known for its strong focus on security. It includes advanced security features such as data encryption, role-based access control, and protection against SQL injection attacks.

Possible disadvantages of MariaDB

• Learning Curve
  For new users, especially those without much experience with relational databases or MySQL, MariaDB can have a steep learning curve. It requires an understanding of SQL, database management, and various configurations.
• Inconsistent Documentation
  While the community is active, the documentation can sometimes be inconsistent or incomplete. This can make troubleshooting and leveraging advanced features more challenging.
• Compatibility Issues
  Although MariaDB aims to be compatible with MySQL, certain features or configurations might not work identically, leading to potential compatibility issues with some applications.
• Fewer Enterprise Features
  Compared to commercial database solutions like Oracle, MariaDB may lack certain enterprise-level features, tools, and support options that large corporations might require.
• Market Adoption
  MariaDB, while popular, does not have as wide of an adoption as MySQL or other big players in the database market, which can be a consideration for integration and support in some environments.

Citus Data features and specs

• Scalability
  Citus Data can scale out across multiple nodes, allowing for horizontal scaling of PostgreSQL. This facilitates handling large volumes of data and high traffic loads efficiently.
• Distributed SQL
  It transforms PostgreSQL into a distributed database, enabling users to run parallel queries across a cluster, which can lead to significant performance improvements.
• PostgreSQL Extension
  As an extension to PostgreSQL, Citus leverages the reliability, robustness, and the rich ecosystem of PostgreSQL, allowing users to continue using familiar PostgreSQL tools and extensions.
• High Availability
  Citus Data provides high availability and disaster recovery options, ensuring that systems can remain operational even during failures.
• Flexible Data Distribution
  Citus allows flexible data distribution methods like sharding, enabling efficient query executions by dividing data across nodes based on application-specific needs.

Possible disadvantages of Citus Data

• Complexity
  Implementing a distributed system with Citus can add complexity to architecture and maintenance compared to a single-node PostgreSQL setup.
• Use Case Suitability
  Citus is best suited for real-time analytics and multi-tenant applications but might not be the best choice for all types of workloads, particularly those that do not require distributed processing.
• Cost
  Running a distributed database may result in higher infrastructure and maintenance costs, especially when scaling out to a large number of nodes.
• Data Replication Overhead
  Although Citus offers high availability, maintaining replicas across multiple nodes can introduce additional overhead and complexity in data consistency management.
• Learning Curve
  There might be a learning curve for teams to understand distributed systems' paradigms and best practices, especially if they are familiar only with traditional single-node databases.
