Embedded Cassandra [Spring Boot Starter]

This project includes AutoConfiguration for Embedded Cassandra.

To configure CassandraBuilder before it builds Cassandra, the application properties can be used. All properties are started with a prefix cassandra.embedded.

#Cassandra config file.
cassandra.embedded.config-file=classpath:cassandra.yaml
#Config properties, that should be merged with properties from cassandra.yaml.
cassandra.embedded.config-properties.native_transport_port=9042
#Cassandra environment variables.
cassandra.embedded.environment-variables.JAVA_HOME=~/java8
#Cassandra native Java Virtual Machine (JVM) Options.
cassandra.embedded.jvm-options=-Xmx512m
#Logger name, that consumes Cassandra STDOUT and STDERR outputs.
cassandra.embedded.logger=Cassandra
#Cassandra instance name.
cassandra.embedded.name=cassandra-0
#Sets if the created Cassandra should have a shutdown hook registered.
cassandra.embedded.register-shutdown-hook=true
#Startup timeout.
cassandra.embedded.startup-timeout=2m
#Cassandra native Java Virtual Machine (JVM) system parameters.
cassandra.embedded.system-properties.[cassandra.jmx.local.port]=7199
#Cassandra version.
cassandra.embedded.version=3.11.9
#Cassandra working directory.
cassandra.embedded.working-directory=target/cassandra-3.11.9
#Additional resources, that should be copied into the working directory.
cassandra.embedded.working-directory-resources.[conf/cassandra.yaml]=classpath:cassandra.yaml

For more advanced builder customizations, you can register an arbitrary number of beans that implement CassandraBuilderConfigurator.

@Configuration(proxyBeanMethods = false)
static class CassandraBuilderConfigurators {

	@Bean
	CassandraBuilderConfigurator cassandraBuilderConfigurator() {
		return new CassandraBuilderConfigurator() {

			@Override
			public void configure(CassandraBuilder builder) {
				//
			}
		};
	}

}

You also can register your own CassandraBuilder bean to get a full control of Cassandra bean instantiation.

@Configuration(proxyBeanMethods = false)
static class CassandraBuilderConfiguration {

	@Bean
	@Scope("prototype")
	CassandraBuilder cassandraBuilder() {
		CassandraBuilder builder = new CassandraBuilder();
		//configure builder
		return builder;
	}

}

EmbeddedCassandraAutoConfiguration can be easily used with @DataCassandraTest annotation for testing Cassandra repositories, just add @ImportAutoConfiguration(EmbeddedCassandraAutoConfiguration.class) to your test.

@DataCassandraTest
@ImportAutoConfiguration(EmbeddedCassandraAutoConfiguration.class)
class CassandraRepositoriesTest {
	//
}

Schema Migration

Embedded Cassandra [Spring Boot Starter] does not support CQL script migration, for this purpose you may try to use the following projects:
