Unveiling GitHub's Secret Blueprint—How to Handle Millions of Transactions Daily
- GitHub is a highly scalable distributed system that processes millions of transactions daily, relying on robust algorithms and architecture.
- Challenges faced by large-scale version control systems include processing millions of daily transactions and efficiently computing file differences.
- GitHub uses diff algorithms like Myers’ Algorithm to track file changes efficiently.
- Myers’ Algorithm finds the shortest edit sequence needed to transform one file version into another.
- A JavaScript implementation of Myers’ Algorithm involves computing the minimum edit distance between two arrays.
- GitHub employs a multi-layered architecture to handle transactions, including API reception, queueing, microservices processing, and database updates.
- JavaScript code simulates GitHub-like transaction processing using Promises for asynchronous parallel processing.
- Key takeaways include asynchronous processing, step-by-step simulation of transactions, and scalability principles.
- GitHub's scalable approach combines optimized diff algorithms, distributed architecture, and parallel transaction processing.
- These techniques are not unique to GitHub and are used in other version control platforms and large-scale data processing systems.
