Andrey Mashenkov commented on IGNITE-13618:
-------------------------------------------
Unfortunatelly, VarHandles/MethodHandle support is limited in Janino.
Seems, it can't process polymorphic signatures and we can't use MethodHandles.
As we can't write plain code and access fields/call method directly therefore
generated code will be very similar to the reflection-based code and
hardly possible it could be more efficient.
> Provide generated and reflection-based class (de)serializers

> Key: IGNITE-13618
> URL: https://issues.apache.org/jira/browse/IGNITE-13618
> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Alexey Goncharuk
> Assignee: Andrey Mashenkov
> Priority: Major
> Labels: iep-54, ignite-3
> Attachments: benchmark-results.txt

>
> Let's prototype object serializer for type-system described in IEP-54, and
> benchmark them to check if generated code approach is a better one.
> * For reflection-based serializer we can use Unsafe (see GridUnsafe class)
> which works fine for previour versions of Ignite.
> * To keep focus on the ticket needs mainly, we can use Janino project for
> code generator.
> * In addition, reflection-based serialized could have a version using Java9+
> VanHandles and it's could be hidden under 'java-9+' maven-profile.
> Hints:
> Javapoet can be used as codegenerator, Janino as a compiler, class loader.
