Whether to eject cache host from the Ketama ring based on failure accrual.
Whether to eject cache host from the Ketama ring based on failure accrual. By default, this is off. When turning on, keep the following caveat in mind: ejection is based on local failure accrual, so your cluster may get different views of the same cache host. With cache updates, this can introduce inconsistency in cache data. In many cases, it's better to eject cache host from a separate mechanism that's based on a global view.
