An auto-plugin that launches Cassandra. at this pre-mature phase, only the very basic functionality works (and only on linux/unix). API is not final, and might (probably will) change down the road. However, the plugin is already usable as is.

Note: The plugin does not work on WindowsOS

Add the following to your project/plugins.sbt file:

addSbtPlugin("com.github.hochgi" % "sbt-cassandra"   % "0.9.1")

In build.sbt, enable the plugin for desired project and specify the version of cassandra against which tests are to be run,

lazy val root = (project in file("."))
  .enablePlugins(CassandraPlugin)
  .settings(Defaults.itSettings: _*)
  .settings(cassandraVersion := "2.1.19")

Cassandra now shuts down by default when tests are done. to disable this behavior, set:

stopCassandraAfterTests := false

cassandra will also clean it's data by default when it stops (after tests or when invoking stopCassandra task explicitly). to disable this behavior, set:

cleanCassandraAfterStop := false

to use special configuration files suited for your use case, use:

cassandraConfigDir := "/path/to/your/conf/dir"

to intialize cassandra with your custom cassandra-cli commands, use:

cassandraCliInit := "/path/to/cassandra-cli/commands/file"

to intialize cassandra with your custom cql commands, use:

cassandraCqlInit := "/path/to/cassandra-cql/commands/file"

timeout for waiting on cassandra to start (default is 20 seconds) can be configured with property (in seconds):

cassandraStartDeadline := 10

to override cassandra configuration, e.g:

configMappings +=  "auto_snapshot" -> true
configMappings ++= Seq(
  "rpc_server_type" -> "sync",
  "data_file_directories" -> {
    val list = new java.util.LinkedList[String]()
    list.add("/path/to/directory/on/disk1")
    list.add("/path/to/directory/on/disk2")
    list.add("/path/to/directory/on/disk3")
    list
  }
)

• don't use both CQL & CLI. choose only one...

• the configMappings key takes a sequence of (String,java.lang.Object), and should be compatible with actual value represented by the key in the yaml file. The configMappings setting should be used to change host, port and cqlPort. The keys for them are:

• host - listen_address

• port - rpc_port

• cqlPort - native_transport_port

to pass java args to cassandra,

cassandraJavaArgs := Seq("-Xmx1G")
