Benchmarking HBase cluster with YCSB

Measuring the performance of a HBase cluster, or benchmarking the cluster, is as important as tuning the cluster itself. The performance characteristics of a HBase cluster that we should measure include at least the following:

  • Overall throughput (operations per second) of the cluster
  • Average latency (average time per operation) of the cluster
  • Minimum latency
  • Maximum latency
  • Distribution of operation latencies

YCSB is a great tool to benchmark performance of HBase clusters. YCSB supports running variable load tests in parallel, to evaluate the insert, update, delete, and read performance of the system. Therefore, you can use YCSB to benchmark for both write-heavy and read-heavy HBase clusters. The record count to ...
