  • Sequential consistency

  • Strong consistency

  • Causal consistency

  • Eventual consistency

In the sequential consistency model, if multiple clients are executing concurrent operations, then:

  • The result of concurrent operations by multiple clients is the same as executing the concurrent operations in arbitrary sequential orders.

  • The concurrent operation by each client is applied in the same sequence specified ...
