What is the core idea of atomicity and invariants?
The core idea is to ensure that certain operations, even in a concurrent or distributed system, appear to happen instantaneously and indivisibly – this is atomicity. In parallel, invariants are properties that must always hold true throughout the execution of a system, regardless of what other processes are doing. My work emphasizes defining these invariants precisely. By designing systems where atomic operations are the building blocks and ensuring that these operations preserve the established invariants, we can reason about system correctness and build robust concurrent software.
