This manual is for an old version of Hazelcast Jet, use the latest stable version.

Programmatic configuration is the simplest way to configure Jet. For example, the following will configure Jet to use only two threads for cooperative execution:

JetConfig config = new JetConfig();
JetInstance jet = Jet.newJetInstance(config);

Any XML configuration files that might be present will be ignored when programmatic configuration is used.
