According to CoinMeta, GitHub has announced a new generation of Git storage architecture codenamed Rubicon. Internal tests have shown that 5,000 AI and agent can work simultaneously within a single code repository, completing 7,200 code pushes per second while maintaining low read latency. In the past, even the busiest code repositories of GitHub could only handle dozens of writes per second for short periods. Now, a large number of AI and agent can be developed in parallel around the clock, with new code being continuously submitted. Each submission may also trigger automatic tests, prompting other agent to download the latest version, thereby increasing the read and write load on the repositories. The solution adopted by GitHub was to separate the processes of "storing code" from "updating branches." Ultimately, GitHub developed a dedicated ref-cas service for managing branch updates, allowing different branches to be updated simultaneously, with conflicts only needing to be resolved when modifying the same branch. The new architecture has achieved 7,200 pushes per second during internal tests and is planned to be rolled out on a larger scale at the beginning of 2027.
