Transactional memory systems represent a paradigm shift in concurrent programming by abstracting low-level lock management and enabling sequences of operations to be executed as atomic transactions.

Figure 1 Aria: (1) Transactions in a batch are executed against the same snapshot; (2) To achieve serializability, the transactions that suffer read-after-write conflict (e.g., T3) and ...

Multiversion concurrency control (MVCC) is a database optimization technique. MVCC creates duplicate copies of records so that data can be safely read and updated at the same time. With MVCC, database ...

Multi-Version Concurrency Control (MVCC) is a widely employed concurrency control mechanism, as it allows for execution modes where readers never block writers. However, most systems implement only ...

In this article I’d like to present a discussion on concurrency handling, concurrency violations and the strategies involved to resolve concurrency conflicts. Concurrency violations: when and why do ...
