# GatlingCql
Gatling DSL support for [Apache Cassandra](https://cassandra.apache.org) CQL. Can be used with [Scylla](https://docs.scylladb.com/using-scylla/cassandra-compatibility/) as well
## Features
Basic Gatling DSL for Apache Cassandra CQL, prepared statements are supported as well.
```scala
import com.datastax.oss.driver.api.core.{ConsistencyLevel, CqlSession}
import io.gatling.core.Predef._
import io.gatling.core.scenario.Simulation
import io.github.gatling.cql.Predef._
class CassandraSimulation extends Simulation {
val keyspace = "test"
val table_name = "test_table"
val session = CqlSession.builder().build()//Your C* session
session.execute(s"""CREATE KEYSPACE IF NOT EXISTS $keyspace
WITH replication = { 'class' : 'SimpleStrategy',
'replication_factor': '1'}""")
session.execute(s"USE $keyspace")
val cqlConfig = cql.session(session) //Initialize Gatling DSL with your session
//Setup
session.execute(s"""CREATE TABLE IF NOT EXISTS $table_name (
id timeuuid,
num int,
str text,
PRIMARY KEY (id)
);
""")
//It's generally not advisable to use secondary indexes in you schema
session.execute(f"""CREATE INDEX IF NOT EXISTS $table_name%s_num_idx
ON $table_name%s (num)""")
//Prepare your statement, we want to be effective, right?
val prepared = session.prepare(s"""INSERT INTO $table_name
(id, num, str)
VALUES
(now(), ?, ?)""")
val random = new util.Random
val feeder = Iterator.continually(
// this feader will "feed" random data into our Sessions
Map(
"randomString" -> random.nextString(20),
"randomNum" -> random.nextInt()
))
val scn = scenario("Two statements").repeat(1) { //Name your scenario
feed(feeder)
.exec(cql("simple SELECT")
// 'execute' can accept a string
// and understands Gatling expression language (EL), i.e. ${randomNum}
.execute("SELECT * FROM test_table WHERE num = ${randomNum}")
.check(rowCount.is(1)))
.exec(cql("prepared INSERT")
// alternatively 'execute' accepts a prepared statement
.execute(prepared)
// you need to provide parameters for that (EL is supported as well)
.withParams(Integer.valueOf(random.nextInt()), "${randomString}")
// and set a ConsistencyLevel optionally
.consistencyLevel(ConsistencyLevel.ANY))
}
setUp(scn.inject(rampUsersPerSec(10) to 100 during (30.seconds)))
.protocols(cqlConfig)
after(session.close())
}
```
## Installation
### For the `gatling-charts-highcharts-bundle` setup
* Get a release TGZ from the [Maven Central](https://repo1.maven.org/maven2/io/github/gatling-cql/gatling-cql/)
* Unpack into Gatling folder: `tar -xjf gatling-cql-3.9.0-1-bundle.tar.gz -C gatling-charts-highcharts-bundle-3.9.0/`
* Run Gatling and you should see `cassandra.CassandraSimulation` in your simulations list
### As a library for your project
Include `gatling-cql` as a dependency to your project. See the [Maven Central Page](https://search.maven.org/artifact/io.github.gatling-cql/gatling-cql/3.9.0-1/jar) for more information for you build tool.
#### Maven Example
You can run your simulations as a part of your build/CI process. See the [Gatling Maven Plugin](https://gatling.io/docs/current/extensions/maven_plugin/) page for more details, please add the following dependency in your POM file.
```xml
io.github.gatling-cql
gatling-cql
3.9.0-1
```
