Java 14 Records¶
Java 14 introduced Record as a lightweight, immutable alternative to POJOs. You can map annotated records as entities.
We have a full example at DataStax-Examples/object-mapper-jvm/record.
Note: records are a preview feature of Java 14. As such the mapper’s support for them is also provided as a preview.
Writing the model¶
Annotate your records like regular classes:
@Entity
record Product(@PartitionKey int id, String description) {}
Records are immutable and use the fluent getter style, but you don’t
need to declare that explicitly with @PropertyStrategy: the mapper detects when it’s processing a
record, and will assume mutable = false, getterStyle = FLUENT by default.
Building¶
You need to build with Java 14, and pass the --enable-preview flag to both the compiler and the
runtime JVM. See pom.xml in the example.
