11. Serializability can be restored by adding synchronization to preserve the dependence on previous iterations.12. Key-value stores can use consistency models ranging from eventual consistency to serializability . 13. The following expressions illustrate the hierarachical ( containment ) relationships between serializability and recoverability classes: 14. Serializability is the basis for the correctness of ( concurrent transactions and ) transactional memory.15. "Commitment ordering " ( CO ) is a special case of conflict serializability . 16. If a serializability conflict is detected from a parallel transaction, then the speculative values are discarded. 17. Transactions aborted due to serializability violation prevention are " restarted " and executed again immediately. 18. Also the above quoted article proposes a relaxed global serializability solution, while referencing the CO work. 19. However, under serializability , B's unlock operation may be moved to " before" 20. A common way to achieve distributed serializability in a latency, which reduces the performance of the system.
