环境准备

• 数据准备：usertable 100 个region 并灌入数据。

                  hbase shell>n_splits=100
                  hbase shell> create 'usertable',{NAME=>'cf',DATA_BLOCK_ENCODING=>'DIFF',COMPRESSION=>'LZO'},{SPLITS => (1...n_splits).map{|i| "user#{1000+i*(9999-1000)/n_splits}"}}

                  

• 工具准备：yz-ycsb
• 命令准备：
  1. 只读装载数据： nohup bin/ycsb load hbase12 -P workloads/nocache_scan_r2 -threads 64 -p columnfamily=cf -p fieldlength=256 -p hdrhistogram.percentiles=95,99,99.9,99.99 >> result.txt &
  2. 只读压测：nohup bin/ycsb run hbase12 -P workloads/nocache_scan_r2 -threads 64 -p columnfamily=cf -p fieldlength=256 -p hdrhistogram.percentiles=95,99,99.9,99.99 >> result.txt &
  3. 只写装载数据：nohup bin/ycsb load hbase12 -P workloads/sync_batch_w2 -threads 64 -p columnfamily=cf -p fieldlength=256 -p hdrhistogram.percentiles=95,99,99.9,99.99 >> result.txt &
  4. 只写压测： nohup bin/ycsb run hbase12 -P workloads/sync_batch_w2 -threads 64 -p columnfamily=cf -p fieldlength=256 -p hdrhistogram.percentiles=95,99,99.9,99.99 >> result.txt &
  5. 读写装载数据：nohup bin/ycsb load hbase12 -P workloads/mix_rw_1 -threads 64 -p columnfamily=cf -p fieldlength=256 -p hdrhistogram.percentiles=95,99,99.9,99.99 >> result.txt &
  6. 读写 nohup bin/ycsb run hbase12 -P workloads/mix_rw_1 -threads 64 -p columnfamily=cf -p fieldlength=256 -p hdrhistogram.percentiles=95,99,99.9,99.99 >> result.txt &
