-----------------------------------------
Summary: Provide support for running cassandra embedded
Key: CASSANDRA-8080
URL: https://issues.apache.org/jira/browse/CASSANDRA-8080
Project: Cassandra
Issue Type: New Feature
Components: Packaging
Reporter: Pablo La Greca
EmbeddedCassandraService allows to run cassandra embedded. What's missing is a
much more clear interface for running cassandra embedded in other applications.
Running cassandra embedded should be much simpler are the user should be able
to run it and configure it using only an API (no configuraiton file required).
The user should be able to do something like:
CassandraSever cassandra = Cassandra.newInstance(new File("cassandra.yaml");
//creates a cassandra node using a configuration file
Or
CassandraConfig config = new CassandraConfig().seeds("ip1", "ip2");
CassandraServer cassandra = Cassandra.newInstance(config);
Implementing this type of functionality should be simple since cassandra
already converts the yaml file to a java class. Also there's a system property
to change the cassandra configuration loader.
It should also be possible to have a client that doesn't need to go through the
wire to communicate with Cassandra, users should be able to do just:
CassandraServer cassandra ...
Session session = cassandra.createSession();
session.execute(String.format("CREATE KEYSPACE IF NOT EXISTS %s WITH
replication = {'class':'SimpleStrategy', 'replication_factor':2};",
applicationName));
This seems to work using directly classes from the package:
org.apache.cassandra.transport.messages
One other thing, but this seems far more complex to do, is that it should be
possible to create several cassandra nodes inside a single JVM. This would
allow to do much more simpler test for cassandra functionality.
