Commutative Variables

In Arcology's optimistic concurrency control, commutative variables are the ones that can take concurrent delta updates in a parallel computing environment as long as these updates don't make the result values to overflow or underflow. The final value of the variables will be the same regardless of how the delta updates are applied.

Supported Data Types

Due to the unique properties of the commutative, only a very limited types can be classified as such, Custom commutative variables aren't supported by Arcology.
