使用YCSB压测Cassandra 3.7  
1、在https://github.com/brianfrankcooper/YCSB/获取源代码（Git或直接下载，我用Git下载到82%时候不动了，于是直接下载zip文件）  
  
  
2、编译源代码  
整个项目编译：mvn clean package  
Cassandra单个编译:mvn -pl com.yahoo.ycsb:cassandra-binding -am clean package  
我选择的是单个编译，比较快

3、编译成功后

![Center][]

显示Cassandra 2.1+ DB Binding .... SUCCESS就说明cassandra编译成功了  其他的不用管，直接去拿/home/yc/YCSB-master/cassandra/target/ycsb-cassandra-binding-0.11.0-SNAPSHOT.tar.gz就行了

#mkidr /usr/local/ycsb/
    #cp ycsb-cassandra-binding-0.11.0-SNAPSHOT.tar.gz /usr/local/ycsb/
    #cd /usr/local/ycsb/
    #tar -zxvf ycsb-cassandra-binding-0.11.0-SNAPSHOT.tar.gz
    #cd ycsb-cassandra-binding-0.11.0

4、用cassandra的cqlsh创建keyspace和cloumn family

(1)新建keyspace:

create keyspace usertable with replication = {'class':'SimpleStrategy', 'replication_factor':1};

(2)新建table也即cloumn family:

create table usertable (y_id varchar primary key,field0 varchar,field1 varchar,field2 varchar,field3 varchar,field4 varchar,field5 varchar,field6 varchar,field7 varchar,field8 varchar,field9 varchar);

5、查看ycsb命令格式

#cd bin
    #ycsb
    usage: ./ycsb command database [options]
    
    
    Commands:
        load           Execute the load phase
        run            Execute the transaction phase
        shell          Interactive mode

        voldemort      https://github.com/brianfrankcooper/YCSB/tree/master/voldemort
    
    
    Options:
        -P file        Specify workload file
        -cp path       Additional Java classpath entries
        -jvm-args args Additional arguments to the JVM
        -p key=value   Override workload property
        -s             Print status to stderr
        -target n      Target ops/sec (default: unthrottled)
        -threads n     Number of client threads (default: 1)
    
    
    Workload Files:
        There are various predefined workloads under workloads/ directory.
        See https://github.com/brianfrankcooper/YCSB/wiki/Core-Properties
        for the list of workload properties.
    ycsb: error: too few arguments

从命令格式里可以看出   -P可以加载一些配置文件    -p可以以键值对的方式加载一些配置   -s每隔一段时间输出执行信息  -threads线程数

6、新建cassandra连接文件(里面的属性可以在源码/home/yc/YCSB-master/cassandra/src/main/java/com/yahoo/ycsb/db/CassandraCQLClient.java中查看)

#vim cassandra.properties
    
    
    hosts = spark131,spark130,spark129   #host列表，用逗号,隔开
    port = 9042
    cassandra.keyspace = usertable    #测试表
    cassandra.username = ershixiong   #cassandra用户名
    cassandra.password = 111111		  #cassandra密码
    cassandra.readconsistencylevel = ANY
    cassandra.writeconsistencylevel = ANY
    cassandra.maxconnections = 100
    cassandra.connecttimeoutmillis = 1000000000
    cassandra.readtimeoutmillis  = 1000000000

7、配置workload

#vim workloads/workloada
    workload=com.yahoo.ycsb.workloads.CoreWorkload
    readallfields=false
    readproportion=0.5
    updateproportion=0.5
    scanproportion=0
    insertproportion=0
    requestdistribution=zipfian
    fieldcount 表示每条数据中的字段数,默认为 10;
    fieldlength 表示每个字段的值的长度,默认为 100;
    readallfields 域用来标识是否读取所有的所有的字段,取值有 ture 或 false;
    readproportion,
    updateproportion,
    scanproportion,
    insertproportion 分别表示该 workload中读、更新、扫描和插入操作占总操作的百分比,这四个值的和为 1;
    requestdistribution 表示数据的分布情况,当前支持 uniform,zipfian 和 latest,默认为 uniform;
    maxscanlength 域主要为扫描操作定义,定义了最大扫描的记录数量,默认为 1000;
    scanlengthdistribution 域也是为扫描操作定义的,为每次扫描的长度定义相应的分布,默认是 uniform;
    insertorder 域主要分两种 ordered 和 hashed,默认为 hashed;
    operationcount 总共的 operation 数量;
    maxexecutiontime 为该 workload 定义了最长的执行时间,单位为 s。
    AverageLatency(平均潜伏期)平均潜伏期（average latency）：指当磁头移动到数据所在的磁道后，然后等待所要的数据块继续转动（半圈或多些、少些）到磁头下的时间，单位为毫秒（ms）。平均潜伏期是越小越好，潜伏期小代表硬盘的读取数据的等待时间短，这就等于具有更高的硬盘数据传输率。

8、

#cd ..
    #./bin/ycsb load cassandra-cql -P workloads/workloada -P cassandra.properties -p columnfamily=usertable -s -threads 20 > ./write7read3-log.log

即  
数据接口名为cassandra-cql  
加载ycsb的配置：workloads/workloada  
加载cassandra的配置：cassandra.properties  
columnfamily名称为usertable  
20个线程执行
