Similar to the `persist` and `merge` operations in the `JpaItemWriter`, this release adds a new operation named
`insert` in the `MongoItemWriter`, which is designed for bulk inserts. This new option performs better than
`upsert` for new items as it does not require an additional lookup to check if items already exist in the target collection.
[[new-item-reader-and-writer-for-redis]]
=== New item reader and writer for Redis
A new `RedisItemReader` is now available in the library of built-in item readers. This reader is based on Spring Data Redis
and can be configured with a `ScanOptions` to scan the key set to read from Redis.
Similarly, a new `RedisItemWriter` based on Spring Data Redis is now part of the writers library. This writer can be configured
with a `RedisTemplate` to write items to Redis.
[[automatic-configuration-of-jobregistrybeanpostprocessor]]
=== Automatic configuration of JobRegistryBeanPostProcessor
When configuring a `JobOperator` in a Spring Batch application, it is necessary to register the jobs in the operator's `JobRegistry`.
This registration process is either done manually or automatically by adding a `JobRegistryBeanPostProcessor` bean to the application
context.
In this release, the default configuration of Spring Batch (ie by using `@EnableBatchProcessing` or extending `DefaultBatchConfiguration`)
now automatically registers a `JobRegistryBeanPostProcessor` bean to the application context. This simplifies the configuration process
and improves the user experience when using a `JobOperator`.
[[ability-to-start-a-job-flow-with-a-decision]]
=== Ability to start a job flow with a decision
When using the XML configuration style, it is possible to start a job flow with a decider thanks to the `<decision>` element.
However, up to version 5.0, it was not possible to achieve the same flow definition with the Java API.
In this release, a new option to start a job flow with a `JobExecutionDecider` was added to the `JobBuilder` API.
This makes both configuration styles more consistent.
[[ability-to-provide-a-custom-jobkeygenerator]]
=== Ability to provide a custom JobKeyGenerator
By default, Spring Batch identifies job instances by calculating an MD5 hash of the identifying job parameters. While it is unlikely to
need to customize this identification process, Spring Batch still provide a strategy interface for users to override the default mechanism
through the `JobKeyGenerator` API.
Up to version 5.0, it was not possible to provide a custom key generator without having to create a custom `JobRepository` and `JobExplorer`.
In this version, it is now possible to provide a custom `JobKeyGenerator` through the factory beans of `JobRepository` and `JobExplorer`.
[[new-documentation-based-on-antora]]
=== New documentation based on Antora
The reference documentation was updated to use https://antora.org[Antora]. This update introduces a number of improvements, including but not limited to:
* Multi-version documentation: it is now possible to navigate from one version to another thanks to the drop down version list in the left side menu.
* Integrated search experience: powered by https://docsearch.algolia.com/[Algolia], the search experience in now better thanks to the integrated search box at the top left of the page
* Improved configuration style toggle: the toggle to switch between the XML and Java configuration styles for code snippets is now located near each sample, rather than the top of each page
