MVCCtas

MVCCtas is a software project that aims to provide a practical implementation of Multiversion Concurrency Control (MVCC) for transactional systems. MVCC is a concurrency control method used in database management systems and other transaction processing systems to provide concurrent access to data while maintaining consistency. Instead of locking data for the duration of a transaction, MVCC creates multiple versions of data items. Each transaction reads a consistent snapshot of the data as it existed at a specific point in time. This allows readers to proceed without blocking writers, and writers to proceed without blocking readers, significantly improving concurrency.

The MVCCtas project focuses on creating a robust and efficient MVCC engine that can be integrated into various applications. Key features of MVCCtas include its ability to handle concurrent read and write operations with minimal contention, its support for transaction isolation levels, and its mechanisms for garbage collection of old data versions. The project emphasizes performance and scalability, aiming to offer a viable solution for high-throughput transactional workloads. Developers can leverage MVCCtas to build applications that require strong consistency guarantees and high levels of concurrency, such as online transaction processing (OLTP) systems, distributed databases, and key-value stores. The project's design principles are geared towards simplicity of integration and ease of use for developers.
