Dolt vs MySQL: What are the differences?

**Key Differences between Dolt and MySQL**

1. **Version Control**: Dolt is a version-controlled database, where every change is automatically versioned, allowing users to track changes easily. MySQL, on the other hand, does not have built-in version control capabilities, requiring users to rely on external tools for version tracking.

2. **Data Sharing**: Dolt allows for easy sharing of databases by simply pushing changes to a remote repository, similar to Git. MySQL, on the other hand, does not provide built-in mechanisms for smooth data sharing, making collaboration more challenging.

3. **Data Integrity**: Dolt ensures data integrity through the versioning system, allowing users to easily roll back to a previous state if needed. MySQL, while offering various constraints for data integrity, does not have built-in versioning capabilities, making rollbacks more complex and manual.

4. **Query Language**: While both Dolt and MySQL support SQL for querying databases, Dolt additionally supports a versioned SQL extension that allows users to query data at different points in time. MySQL does not have this feature, limiting its capabilities in terms of temporal queries.

5. **Performance**: MySQL is widely known for its strong performance in traditional database operations, especially in handling large datasets. Dolt, on the other hand, may experience some performance trade-offs due to the additional versioning overhead, especially in scenarios where frequent data changes occur.

6. **Database Size**: Dolt databases tend to be larger in size compared to MySQL databases due to the nature of versioning and storing historical data. This difference in database size can impact storage requirements and performance, especially in scenarios where storage capacity is a concern.

**In Summary, Dolt offers built-in version control and data sharing capabilities, while MySQL focuses on performance and traditional database operations.**
