Test Pegasus

This section describes how to run YCSB on Pegasus.

1. Start Pegasus service

Ask to Pegasus cluster manager to start the cluster, and create table usertable for test.

If you want to use a different table name, please config the table option in workloads/workload_pegasus.

2. Install Java and Maven

See step 2 in mongodb/README.md.

3. Set up YCSB

Before set up YCSB, you should install Pegasus Java Client firstly:

cd scripts && sh recompile_thrift.sh && cd -
mvn spotless:apply
mvn clean install -DskipTests

Git clone YCSB and build it:

git clone https://github.com/XiaoMi/pegasus-YCSB.git
cd pegasus-YCSB
mvn -Dcheckstyle.skip=true -DskipTests -pl com.yahoo.ycsb:pegasus-binding -am clean package

4. Configuration

A default pegasus configuration file is provided in pegasus/conf/pegasus.properties.

A default log4j configuration file is provided in pegasus/conf/log4j.properties.

Because pegasus/conf is added into classpath by default, so these configuration files will be found automatically. Also You can specify configuration file on the command line via -p, e.g.:

# example for specifying. If you have executed this command, skip the "Load the data" phase in section 5.
./bin/ycsb load pegasus -s -P workloads/workload_pegasus \
    -p "pegasus.config=file://./pegasus/conf/pegasus.properties" > outputLoad.txt

5. Load data and run tests

Load the data:

./bin/ycsb load pegasus -s -P workloads/workload_pegasus > outputLoad.txt

Run the workload test:

./bin/ycsb run pegasus -s -P workloads/workload_pegasus > outputRun.txt

6. Distributed running tests

Generate pegasus-YCSB-${VERSION}.tar.gz package:

./pack_pegasus.sh

Transfer package to target machines, then:

tar xfz pegasus-YCSB-${VERSION}.tar.gz
cd pegasus-YCSB-${VERSION}
./start.sh <load|run>

Getting Started

1. Download the latest release of YCSB:

   curl -O --location https://github.com/brianfrankcooper/YCSB/releases/download/0.10.0/ycsb-0.10.0.tar.gz
   tar xfvz ycsb-0.10.0.tar.gz
   cd ycsb-0.10.0

2. Set up a database to benchmark. There is a README file under each binding directory.

3. Run YCSB command.

   On Linux:

   bin/ycsb.sh load basic -P workloads/workloada
   bin/ycsb.sh run basic -P workloads/workloada

   On Windows:

   bin/ycsb.bat load basic -P workloads\workloada
   bin/ycsb.bat run basic -P workloads\workloada

Running the ycsb command without any argument will print the usage.

See https://github.com/brianfrankcooper/YCSB/wiki/Running-a-Workload for a detailed documentation on how to run a workload.

See https://github.com/brianfrankcooper/YCSB/wiki/Core-Properties for the list of available workload properties.

Building from source

YCSB requires the use of Maven 3; if you use Maven 2, you may see errors such as these.

To build the full distribution, with all database bindings:

mvn clean package

To build a single database binding:

mvn -pl com.yahoo.ycsb:mongodb-binding -am clean package
