Transient Fields

The default MicroStream implementation fully supports the Java transient field modifier. Class members marked transient will not be persisted.

public class User
{
	private String username;

	//do not persist the users password
	private transient String password;
}

It is possible to override the default behavior by implementing a custom PersistenceFieldEvaluator.

PersistenceFieldEvaluator fieldEvaluator =
	(clazz, field) -> !field.getName().startsWith("_");

EmbeddedStorageManager storage = EmbeddedStorage.Foundation()
	.onConnectionFoundation(
		c -> c.setFieldEvaluatorPersistable(fieldEvaluator)
	)
	.createEmbeddedStorageManager()
	.start();
