The document discusses techniques for rigorously measuring Apache HBase performance in both standalone and multi-tenant environments. It introduces the Yahoo! Cloud Serving Benchmark (YCSB) and best practices for cluster setup, workload generation, data loading, and measurement. These include pre-splitting tables, warming caches, setting target throughput, and using appropriate workload distributions. The document also covers challenges in achieving good multi-tenant performance across HBase, MapReduce and Apache Solr.
