中被称为粗粒度锁。
例如，在财务系统中的客户级别上：一个粗粒度锁会锁定该客户的所有帐户，另一个锁则可锁定全部保险策略。
An example might be at the customer level in a financial system: one coarse grained lock could be to lock all accounts for the customer, another could be to lock all insurance policies.
锁升级是将许多较细粒度的锁转换成数量更少的较粗粒度的锁的过程，这样可以减少系统开销，但却增加了并发争用的可能性。
Lock escalation is the process of converting many fine-grain locks into fewer coarse-grain locks, reducing system overhead while increasing the probability of concurrency contention.
