Transactional Memory: Two-phase Locking and Invisible Reads

This lecture provides a historical perspective on databases, theory, language, architecture, and hardware related to transactional memory. It covers the two-phase locking mechanism, the TM API, and the concept of invisible reads. The instructor discusses the importance of transactional memory in the context of multi-core processors and presents different approaches such as DSTM. The lecture explores contention managers and the implications of aborting transactions, emphasizing the challenges and benefits of using transactional memory in modern computing systems.
