On behalf of the Spring Batch team, I am pleased to announce the general availability of Spring Batch 4.2, which includes a number of new features and performance improvements!

New Features

Spring Batch 4.2 includes the following new features:

• Batch Metrics with Micrometer
• Support for Apache Kafka
• Support for Apache Avro

Batch Metrics with Micrometer

Spring Batch has always provided users with various metrics through the job repository. However, the ability to consume these metrics and react to them in real time has been muted by the use of a database as the metrics store. This release introduces a new feature that lets you monitor your batch jobs by using a true metrics store through Micrometer. By default, Spring Batch collects metrics (such as job duration, step duration, item read and write throughput, and others) and registers them in Micrometer’s global metrics registry under the spring.batch…

The most notable features are:

• ConnectionFactory routing through AbstractRoutingConnectionFactory.

• Propagation and reset of Auto-Commit and Isolation Level control through TransactionDefinition.
• Support for Entity-level converters.
