5.5.0

The main feature of this release is a new experimental API that offers a convenient query execution option within a managed transaction with automatic retries on errors eligible for retrying.

Sample usage:

var eagerResult = driver.queryTask("CREATE (n{field: $value}) RETURN n")
                    .withParameters(Map.of("value", "5"))
                    .execute();

In addition, it is also possible to provide a java.util.stream.Collector implementation to collect Records to a desired final value:

var result = driver.queryTask("UNWIND range(0, 5) as N RETURN N")
        .execute(Collectors.mapping(record -> record.get("N").asLong(), Collectors.toList()));

See the QueryTask documentation for more details.

5.2.0

This is a refinement release that brings several new features, improvements and dependency updates.

This update introduces a new reactive session org.neo4j.driver.reactivestreams.ReactiveSession that is similar to the deprecated org.neo4j.driver.reactive.RxSession and includes improvements introduced with org.neo4j.driver.reactive.ReactiveSession.

Following these updates, the driver supports 2 reactive sessions:

• org.neo4j.driver.reactive.ReactiveSession - uses Java Flow API
• org.neo4j.driver.reactivestreams.ReactiveSession - uses Reactive Streams API

In addition, this update brings new methods for session instantiation. See the sample usage below:

var synchronousSession = driver.session(Session.class);
var asynchronousSession = driver.session(AsyncSession.class);
var reactiveSession1 = driver.session(org.neo4j.driver.reactive.ReactiveSession.class);
var reactiveSession2 = driver.session(org.neo4j.driver.reactivestreams.ReactiveSession.class);
var reactiveSession3 = driver.session(org.neo4j.driver.reactive.RxSession.class);

The following methods have been deprecated:

• asyncSession
• reactiveSession

Driver's TypeSystem is now accessible via TypeSystem.getDefault().
