This release includes an optimisation that removes a network roundtrip in the ExecutableQuery
. #1482
By removing the round trip when using the ExecutableQuery
the network overhead of running the query is reduced by up to 1/3rd. Most benefit will be seen when running lots of single queries with few records that complete quickly on the server.

methods. This aims to ensure that the transaction is rolled back and the acquired connection is returned back to the connection pool. #1457
In addition, the driver will round up sub millisecond values in the transaction timeout configuration. #1451
Furthermore, an experimental BlockHound integration has been introduced. #1450

For more details on this feature, please see the #1396 update and the API documentation.
The org.neo4j.driver:neo4j-java-driver-all
artifact includes an explicit module declaration for Java Platform Module System (JMPS).

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 Record
s 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.

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

is now accessible via TypeSystem.getDefault()
.

The driver has been upgraded to Java 17 and it is the baseline Java version for this release.
The org.neo4j.driver:neo4j-java-driver
artifact no longer includes shaded Netty and Project Reactor dependencies and replaces the org.neo4j.driver:neo4j-java-driver-slim
introduced in 4.4 series.
A new org.neo4j.driver:neo4j-java-driver-all
artifact includes shaded Netty and Project Reactor dependencies dependencies and is similar to the original packaging of the org.neo4j.driver:neo4j-java-driver
before this update.
The org.neo4j.driver:neo4j-java-driver
includes an explicit module declaration for Java Platform Module System (JMPS). The module name remains unchanged.
A new ReactiveSession
has been introduced that includes API improvement and is based on Java Flow API. The RxSession
has been deprecated.
A RetryableException
marker interface has been introduced to enable easier checking of retryable driver exceptions.
A new experimental BookmarkManager
feature has been introduced to allow simpler bookmark management, including multi-session level. This is an opt-in feature that is available via SessionConfig
.
