Bonree Data Technology migrated from ZooKeeper to ClickHouse Keeper for their observability platform, resulting in significant improvements in performance and resource efficiency. The migration achieved over 75% reduction in CPU and memory usage, with IO overhead decreasing by 8 times and performance improving nearly 8 times. ClickHouse Keeper's compatibility with ZooKeeper client protocols allowed for a smooth transition without server-side modifications. Additionally, the use of C++ in ClickHouse Keeper enhanced overall service stability and improved resource usage efficiency compared to Java-based ZooKeeper.
