Leader election with: Etcd vs Zookeeper vs Hazelcast

C# - etcd GRPC Client Basic Auth

QUESTION

Leader election with: Etcd vs Zookeeper vs Hazelcast

Asked 2019-Sep-05 at 11:56

We are choosing the best option for implementing a leader election for our service (written in Java) comprised of multiple (e.g., 3) instances for high availability. Our goal is to have only a single instance active at any given time.

Would be great to hear your opinion about the following options:

1) Hazelcast. Using "quorum" and a lock we can implement a leader election. However, we can run into a split-brain problem where for some time two leaders may be present. Also, it seems that Hazelcast does not support SSL.

2) Zookeeper. We can implement leader election on top of a Zookeeper ensemble (where a ZK node is run on each instance of our service). Does Zookeeper provide better consistency guarantees than Hazelcast? Does it also suffer from the split-brain problem?

3) Etcd. We can use the Jetcd library which seems like the most modern and robust technology. Is it really better in terms of consistency than Zookeeper?

Thank you.

1) Hazelcast, by version 3.12, provides a CPSubsystem which is a CP system in terms of CAP and built using Raft consensus algorithm inside the Hazelcast cluster. CPSubsytem has a distributed lock implementation called FencedLock which can be used to implement a leader election.

For more information about CPSubsystem and FencedLock see;

Hazelcast versions before 3.12 are not suitable for leader election. As you already mentioned, it can choose availability during network splits, which can lead to election of multiple leaders.

2) Zookeeper doesn't suffer from the mentioned split-brain problem, you will not observe multiple leaders when network split happens. Zookeeper is built on ZAB atomic broadcast protocol.

3) Etcd is using Raft consensus protocol. Raft and ZAB have similar consistency guarantees, which both can be used to implement a leader election process.

Disclaimer: I work at Hazelcast.
