The fully transactional, cloud-ready, distributed database

MySQL :: MySQL Community Edition

Immutability
Datomic employs an append-only data model where data is never overwritten but instead appended, ensuring historical data is always available and providing strong consistency.
Time Travel Queries
Datomic allows you to query the database as of any point in time, facilitating auditing and debugging by allowing easy access to historical data states.
Rich Data Model
Supports complex data types like maps and sets directly within its schema, providing a flexible way to represent data.
ACID Transactions
Datomic supports fully ACID-compliant transactions, ensuring reliable and predictable database operations.
Scalability
Separates storage and compute, allowing for horizontal scaling of read operations, making it suitable for handling large datasets.
Query Flexibility
Offers a powerful query language that supports recursive queries, making it suitable for complex data retrieval needs.

Complexity
The architecture of Datomic can be complex to understand and implement, particularly for teams unfamiliar with its design principles.
Cost
Can be expensive to operate, especially in a cloud environment, where costs increase with the amount of data stored and the compute resources required.
Limited Write Throughput
Due to its append-only design, Datomic can have limited write throughput, which may not be suitable for applications with heavy write requirements.
Closed Source
Datomic is a proprietary database system, which may not appeal to organizations that prefer open-source solutions.
Learning Curve
Requires a learning curve as its conceptual model and query language are different from traditional databases, potentially requiring additional training.
Dependency on AWS
Relying on AWS ecosystem for the storage backend can limit choices for deployment environments, impacting flexibility.

Cost
MySQL Community Edition is free and open-source, making it accessible for small businesses, startups, and individual developers without incurring licensing costs.
Community Support
A large and active community offers extensive resources, including forums, tutorials, and documentation, aiding in troubleshooting and knowledge sharing.
Compatibility
Supports a wide range of platforms including Windows, Linux, and macOS, and can integrate with various programming languages and web frameworks.
Reliability
Proven track record for reliability and performance in production environments, widely used by organizations of all sizes.
Regular Updates
Frequent updates and patches from the MySQL development team ensure that the software stays secure and up-to-date with new features.
ACID Compliance
Supports Atomicity, Consistency, Isolation, Durability (ACID) properties, which are essential for ensuring reliable transactions.

Limited Enterprise Features
Lacks some advanced features like sophisticated replication, clustering, and advanced security options available in MySQL Enterprise Edition.
Support
No official customer support is available; users must rely on community support, which could lead to longer resolution times for critical issues.
Performance
In very high-transaction environments, performance can lag compared to some proprietary database systems with more optimization tools.
Scalability
While suitable for small to medium-sized applications, it may not scale as effectively for very large-scale, high-traffic applications without significant customization.
InnoDB Limitations
The default storage engine, InnoDB, while robust, lacks advanced indexing options available in other database systems, potentially limiting read performance.
Backup and Recovery Tools
Built-in backup tools are basic and may not meet the needs of more complex backup strategies compared to enterprise-grade solutions.
