Hi folks I am benchmarking the performance of Zookeeper using five servers. I am just testing the write workload (CREATE node) in both mode (sync and async). The benchmark code is designed to measure the performance of a ZooKeeper ensemble for a predetermined length of time (e.g., sustained handling of create requests for 5 minutes seconds).
It seems easy to measure the latency and throughput in Sync mode as there is not any process run in the background. Measuring latency Using Async mode can be achieved by stat command (four word command). However, I am struggling to measure the throughput in Async mode because when the 5 minutes elapsed, the requests are still processing in Zookeeper and after some time will stop. Also when I try to use the stat command I see the following output: Latency min/avg/max: 1/375/1259 Received: 201870 Sent: 201619 Connections: 1 Outstanding: 0 Zxid: 0x1000ff2c7 Mode: follower Node count: 1032597 In the above output there is Node count, this can be expressed as total number of nodes created, but the finished time is unknown. I think it is not true to say the finished time is 5 minutes, because the processing request is not finished when 5 minutes are elapsed because of Async mode. Can you share knowledge? How can I solve this problem? Can anyone advise me for best strategy of testing and measuring the performance of write workload in Zookeeper?
