A native MySQL driver for Crystal written entirely in Crystal, offering non-blocking I/O and significant performance improvements.
crystal-mysql is a MySQL database driver implemented natively in the Crystal programming language. It provides a high-performance connector that avoids external C library dependencies, enabling non-blocking I/O and significant speed improvements for database operations in Crystal applications.
Crystal developers building applications that require MySQL database connectivity, particularly those working on web servers or concurrent systems where non-blocking database access is critical.
Developers choose crystal-mysql for its pure Crystal implementation, which eliminates data copying overhead and thread blocking, resulting in 2x-3x performance gains and better integration with Crystal's concurrency model compared to external library alternatives.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Implemented entirely in Crystal without external C dependencies, eliminating data copying overhead and showing 2x-3x speed improvements in initial tests over traditional drivers.
Designed to avoid thread blocking during database operations, it seamlessly integrates with Crystal's concurrency model, making it ideal for high-concurrency web servers.
Implements MySQL's binary protocol for prepared statements, enhancing query performance and security compared to text-based protocols.
Supports TCP connections, Unix sockets, and configurable SSL/TLS modes with parameters like ssl-mode, allowing versatile and secure deployment scenarios.
The driver is explicitly marked as a work in progress, meaning it may lack advanced features, have unresolved bugs, or undergo breaking changes, posing risks for production use.
Users may encounter authentication protocol errors requiring manual server configuration, such as creating new users with specific plugins, as noted in the usage examples, adding setup complexity.
Relies on external crystal-db documentation, and being part of Crystal's smaller ecosystem, it has fewer community resources and examples compared to mainstream database drivers.
