Method Summary

Modifier and Type	Method and Description
default void	lock(LockRequest request, io.grpc.stub.StreamObserver<LockResponse> responseObserver) Lock acquires a distributed shared lock on a given named lock.

Method Detail

lock

default void lock(LockRequest request,
                  io.grpc.stub.StreamObserver<LockResponse> responseObserver)

 Lock acquires a distributed shared lock on a given named lock.
 On success, it will return a unique key that exists so long as the
 lock is held by the caller. This key can be used in conjunction with
 transactions to safely ensure updates to etcd only occur while holding
 lock ownership. The lock is held until Unlock is called on the key or the
 lease associate with the owner expires.
 

unlock

default void unlock(UnlockRequest request,
                    io.grpc.stub.StreamObserver<UnlockResponse> responseObserver)

 Unlock takes a key returned by Lock and releases the hold on lock. The
 next Lock caller waiting for the lock will then be woken up and given
 ownership of the lock.
