[−][src]Enum raft::ReadOnlyOption
Determines the relative safety of and consistency of read only requests.
Variants
Safe
Safe guarantees the linearizability of the read only request by communicating with the quorum. It is the default and suggested option.
LeaseBased
LeaseBased ensures linearizability of the read only request by relying on the leader lease. It can be affected by clock drift. If the clock drift is unbounded, leader might keep the lease longer than it should (clock can move backward/pause without any bound). ReadIndex is not safe in that case.
