Three node replica set testing with YCSB

Recommended Tests on MongoDB

The most common three tests are 95/5 (95% read and 5% update), 100/0 (100% read and 0% update) and 90/10 (90% read and 10% update). In real world testing it’s recommended to run a 95/5 test.

Once you have loaded the dataset, run the selected test for approximately five minutes. This will allow the system to warm up before you start collecting performance data. The goal is to reach a high CPU utilization (90+%). Adjusting the number of threads, operationscount and recordscount can help you achieve this. Examples below may need to be adjusted based on the instance type you selected.

Load dataset

    

        
        
./bin/ycsb load mongodb -s  -P workloads/workloadb  -p mongodb.url=mongodb://localhost:27017 -p compressibility=2 -p fieldlengthdistribution=zipfian -p minfieldlength=50 -threads 64 -p recordcount=20000000

    

Run 95/5 test:

    

        
        
./bin/ycsb run mongodb -s  -P workloads/workloadb  -p mongodb.url=mongodb://localhost:27017 -p minfieldlength=50 -p compressibility=2 -p maxexecutiontime=120 -threads 64 -p operationcount=40000000 -p recordcount=20000000 -p requestdistribution=zipfian -p readproportion=0.95 -p updateproportion=0.05

    

Run 100/0 test:

    

        
        
./bin/ycsb run mongodb -s  -P workloads/workloadc  -p mongodb.url=mongodb://localhost:27017 -p minfieldlength=50 -p compressibility=2 -p maxexecutiontime=120 -threads 64 -p operationcount=40000000 -p recordcount=20000000 -p requestdistribution=zipfian -p readproportion=1.0 -p updateproportion=0.0

    

Run 90/10 test:

    

        
        
./bin/ycsb run mongodb -s  -P workloads/workloadb  -p mongodb.url=mongodb://localhost:27017 -p minfieldlength=50 -p compressibility=2 -p maxexecutiontime=120 -threads 64 -p operationcount=40000000 -p recordcount=20000000  -p requestdistribution=zipfian -p readproportion=0.90 -p updateproportion=0.10
