4.4.4

The highlight of this release is support for Micrometer metrics that comes with experimental status.

In addition, it brings several general improvements and dependency updates.

To enable Micrometer metrics, you need to:

  • include Micrometer dependencies on classpath
  • enable Micrometer metrics via driver configuration

Sample driver configuration:

var config = Config.builder()
		.withMetricsAdapter(MetricsAdapter.MICROMETER)
		.build();

var driver = GraphDatabase.driver(url, AuthTokens.basic(username, password), config);

At this stage we only support the global registry that is discovered automatically.
