MySQL VS MongoDB 你会如何选择？

`id` int(10) unsigned NOT NULL auto_increment,
`k` int(10) unsigned NOT NULL default ‘0’,
`c` char(120) NOT NULL default ”,
`pad` char(60) NOT NULL default ”,
PRIMARY KEY (`id`),
KEY `k` (`k`));

4.3.2 ycsb

4.3.2.1 准备工作

编辑workload文件,分别修改readproportion、updateproportion、insertproportion为相应的值并分别命名为workload_select、workload_update、workload_insert、workload_complex比如只读测试workload_select文件内容：

workload=com.yahoo.ycsb.workloads.CoreWorkload
recordcount=${size}
operationcount=${size}
insertstart=0
fieldcount=4
fieldlength=100
readallfields=true
writeallfields=false
fieldlengthdistribution=zipfian
readproportion=1
updateproportion=0
insertproportion=0
requestdistribution=zipfian
table=ycsb_test
maxexecutiontime=1800

4.3.2.2 只读测试

测试命令：

./bin/ycsb load mongodb -s -threads 1 -P workloads/workload_select
./bin/ycsb run mongodb -s -threads 1 -P workloads/workload_select

4.3.2.3 只更新测试

测试命令：

./bin/ycsb load mongodb -s -threads 1 -P workloads/workload_update
./bin/ycsb run mongodb -s -threads 1 -P workloads/workload_update

4.3.2.4 只插入测试

测试命令：

./bin/ycsb load mongodb -s -threads 1 -P workloads/workload_insert
./bin/ycsb run mongodb -s -threads 1 -P workloads/workload_insert

4.3.2.5 混合模式测试

测试命令：

./bin/ycsb load mongodb -s -threads 1 -P workloads/workload_complex
./bin/ycsb run mongodb -s -threads 1 -P workloads/workload_complex

参数含义请参考上面的使用说明章节.
