Hibernate Search is a community driven project and as such the roadmap constantly evolves to reflect the users needs.
You can find a finer grained roadmap in our issue tracker but this page is a good and concise view of where we are going.
Dates are generally omitted: milestones are released regularly, the Final release is tagged when it’s considered stable.
Hibernate Search 6.1
- Restore the WildFly integration
-
The WildFly integration was removed in 6.0 to reduce the work load. We will restore it in 6.1.
- First-class support for clustered applications
-
Hibernate Search 6.0 only allows single-node applications, or multi-node applications where each node works independently, simply sending events to an Elasticsearch cluster.
This does not account for several challenges that we will address in 6.1:
-
When each node sends updates to Elasticsearch independently, conflicts may arise when entities are updated simultaneously on different nodes. There is a need to prevent, or at least resolve, these conflicts.
-
For some use cases where maintenance downtime is not acceptable, Hibernate Search needs to provide hot updates at the cluster level: allow to boot application nodes with the new mapping, while some application nodes with the old mapping are still running.
-
Hibernate Search 6.x
- Restore the OSGi integration
-
The OSGi integration was removed in 6.0 to reduce the work load. We will restore it in 6.1 if there is demand for it. Vote here.
- Free-form indexing
-
We’re planning to decouple the metadata definition from annotated java classes, to allow better indexing of other more flexible sources; for example to make it easier to index data structured in the JSON format, or other formats whose schema is not known at compile time.
