ClickHouse Keeper: Efficient Apache ZooKeeper Alternative Created with C++ and Raft

ClickHouse project team created an in-house replacement for Apache Zookeeper as it needed a more efficient implementation that would also address some of Zookeeper's shortcomings. Now, ClickHouse Keeper is an essential part of the ClickHouse project and a cornerstone of this open-source analytical database, but can also be used independently for many distributed coordination use cases.
