openHalo
An open-source database project with protocol-level MySQL compatibility, filling international gaps and demonstrating China's database technology prowess.
Technical Mission
Protocol-level MySQL compatibility is one of Halo's core capabilities. In 2024, NEXTGRES announced a similar PostgreSQL-based MySQL migration capability but underestimated the complexity. Despite a strong team, the NEXTGRES project has effectively failed.
Original Intention
We realized we might have unknowingly stepped into the forefront of the world, filling an international gap. From the beginning of our venture, we have always adhered to the sentiment of serving the country through technology, aiming to increase the voice of Chinese technicians internationally.
Project Vision
After careful evaluation, we decided to open-source our MySQL compatibility capability. We hope this project will enhance the international influence of Chinese databases, win a good reputation for domestic databases, and showcase the capabilities of Chinese technicians.
