What would you like?
Similar to the Python SDK's decorators we can offer annotations in Java for customers who prefer an annotation-driven programming style rather than imperative/functional programming style when implementing durable operations.
For example, @durable_step from Python can become @DurableStep in Java. The customer would be able to annotate an arbitrary method with such a (configurable) annotation and call it. The SDK will take care of the internal wiring to wrap the method logic in a context.step(...).
This issue tracks the creation of a design document for such an annotation processors.
Some technical implementation options include:
- Using reflection at runtime and proxies to implement annotation.
- Using annotation processors (similar to Dagger). Technical feasibility unclear.
- Using maven/gradle plugins at build time to manipulate bytecode weaving in the logic of the processed annotation
- Some libraries in the bytecode manipulation space include ASM, ByteBuddy, Gizmo, Java 24+ Classfile API
