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.

Apache Cassandra features and specs

• Scalability
  Apache Cassandra is designed for linear scalability and can handle large volumes of data across many commodity servers without a single point of failure.
• High Availability
  Cassandra ensures high availability by replicating data across multiple nodes. Even if some nodes fail, the system remains operational.
• Performance
  It provides fast writes and reads by using a peer-to-peer architecture, making it highly suitable for applications requiring quick data access.
• Flexible Data Model
  Cassandra supports a flexible schema, allowing users to add new columns to a table at any time, making it adaptable for various use cases.
• Geographical Distribution
  Data can be distributed across multiple data centers, ensuring low-latency access for geographically distributed users.
• No Single Point of Failure
  Its decentralized nature ensures there is no single point of failure, which enhances resilience and fault-tolerance.

Possible disadvantages of Apache Cassandra

• Complexity
  Managing and configuring Cassandra can be complex, requiring specialized knowledge and skills for optimal performance.
• Eventual Consistency
  Cassandra follows an eventual consistency model, meaning that there might be a delay before all nodes have the latest data, which may not be suitable for all use cases.
• Write-heavy Operations
  Although Cassandra handles writes efficiently, write-heavy workloads can lead to compaction issues and increased read latency.
• Limited Query Capabilities
  Cassandra's query capabilities are relatively limited compared to traditional RDBMS, lacking support for complex joins and aggregations.
• Maintenance Overhead
  Regular maintenance tasks such as node repair and compaction are necessary to ensure optimal performance, adding to the administrative overhead.
• Tooling and Ecosystem
  While the ecosystem for Cassandra is growing, it is still not as extensive or mature as those for some other database technologies.
