Ted Yu updated HBASE-20601: --------------------------- Release Note: 1. Add multiPut support Set --multiPut=number to enable batchput(meanwhile, --autoflush need be set to false) 2. Add Connection Count support Added a new parameter connCount to PE. set --connCount=2 means all threads will share 2 connections. oneCon option takes precedence over connCount 3. Add avg RT and avg TPS/QPS statstic for all threads 4. Delete some redundant code Now RandomWriteTest is inherited from SequentialWrite. was: 1.

Add multiPut support > Though we have BufferedMutator, sometimes we need to benchmark batch put in a > certain number. > Set --multiPut=number to enable batchput(meanwhile, --autoflush need be set > to false) > 2. Add Connection Number support > Before, there is only on parameter to control the connection used by threads. > oneCon=true means all threads use one connection, false means each thread has > it own connection. > When thread number is high and oneCon=false, we noticed high context switch > frequency in the machine which PE run on, disturbing the benchmark > results(each connection has its own netty worker threads, 2*CPU IIRC). > So, added a new parameter connCount to PE. set --connCount=2 means all > threads will share 2 connections. > 3. Add avg RT and avg TPS/QPS statstic for all threads > Useful when we want to meansure the total throughtput of the cluster > 4. Delete some redundant code > Now RandomWriteTest is inherited from SequentialWrite. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
