neo4j-java-driver

In this new driver version, we'd like to present a new routing driver with built-in routing to a Neo4j 3.1+ causal cluster. To use the new routing driver, use bolt+routing scheme instead of bolt in the uri when creating the driver.

If you still prefer your own routing or you are still working with the old HA cluster, then bolt scheme gives you all the same old behaviors with minor improvements.

To see the whole story, please take a look at the 1.1 changelog

A new release of the 1.1 driver.
This release introduces a few small improvements in the API. For the full details of the new changes, pls find them in the changelog

Proper handling of cluster failures for transactions. See changelog for more info.

Fixed a few bugs related to buffer management and improved few error messages. See changelog for more info

Bug fixes for discovery and routing.

See details in the 1.1 changelog

Minor improvement in error messages.

This release introduces the new support of routing cypher statements to a Neo4j 3.1+ cluster and running statements on the cluster directly.
More details info and bug fixes could be found in changelog

The first release of driver 1.1. See more info in the changelog.
More new features coming soon!

We present a newly designed session pool, which provides a safer resource management than the previous one. With this new pool, the maximum amount of sessions is no longer limited, instead you will get as much sessions as your application demands. This session pool uses IdleSessionPool to buffer the sessions that are not used currently but are available to be reused immediately. Therefore with this new change, the previous connectionPoolSize, which specifies the max number of connections per URL for this driver is deprecated.

Fixed a rare dechunking bug where driver mis-reads chunk size when reading bytes across input buffer border.

A fully new API for Neo4j, and a client implementation of the Bolt V1 protocol.

The current driver version 1.0 works with Neo4j 3.0 databases.

For details about how to use the driver, please refer to driver manual and Java driver API documentation

For more information about changes from pre-release versions, please refer to change log

Improved a few methods semantics in the result API.
See the changelog for more details.

See change log https://github.com/neo4j/neo4j-java-driver/wiki/1.0-changelog

• Improved the way to configure encryption by introducing EncryptionLevel and TrustStrategy to replace the old TlsEnabled and TlsAuthConfig.
• Introduced auth capabilities where on the creation of the driver, authentication credentials could be passed to the driver so that the server would be able to authenticate the driver user.
• Change ResultCursor to Iterator
• Improved discoverability of API
• Severity level is now exposed on Notifications
• Summary#updateStatistics renamed to Summary#counters
• StatementResult#summarize renamed to StatementResult#consume

The main changes in this release are listed as follows:

• Added support for streaming, which means that we no longer need to wait for the whole result of a Cypher statement to fully streamed back before visiting the first record in the result. Instead, we now could immediately visit the records that already arrive without blocking for the last record in the result to arrive!
• Added variants of ResultCursor#single and ResultCursor#first for simplified access and added support to call first and single multiple times.
• Renamed ConfigBuilder#withConnectionPoolSize to ConfigBuilder#withMaxSessions.

The main changes in this milestone release are listed as follows:

• Upgraded Bolt protocol implementation to support new preamble in handshake
• API modifications based on M01 feedback around Values, Result and Type interfaces
• Move API into v1 package to allow future releases with multiple API versions in parallel
• Few bug fixes.
