Gatling DSE Stress

Building

To build a jar run sbt assembly. The jar will be found in target/scala-2.12/gatling-dse-stress-assembly-1.2.2.jar

Running a Simulation

First build the jar using sbt then run the jar with the path of the sim name java -jar gatling-dse-stress-1.2.2.jar run {SimPath} and example is java -jar gatling-dse-sims-1.2.2.jar run examples.sims.cql.WriteOrderSimulation

Configuration

Project configs can be found in the src/main/resources the application.conf is the file to set the Simulation and Cassandra settings.

During run you can override part or all of the application settings by using -Dconfig.file={filePath}. If you want to override a single setting only just use the path of the config ie -Dcassandra.hosts=127.0.0.1. This single setting can be used for any value in the application.conf file as well.
