In this repo I would like to show 4 strategies of concurrency control for writing data using Python SQLAlchemy ORM and PostgresSQL (however this examples could be easily transformed to plain SQL).
Concurrency Control simulation using Two-Phase Locking (2PL), OCC, and MVCC Timestamp Ordering Protocol
Examples of applying pessimistic and optimistic concurrency control with AWS DynamoDB.
