Andrey Mashenkov commented on IGNITE-13618:
-------------------------------------------
[~agoncharuk], I've done the implementation both serializers, and start with
benchmark implementation.
Code can be found at ignite-13618 branch.
I'm not sure if it make sense to add VarHandle-based version right now?
What benchmark are you expect to be?
I see next cases
# Key-val pairs of simple types:
** fixed-len, e.g. (long, long) as most popular cases or (uuid, uuid)?
** varlen string (64,256, 1k), e.g. encoding may costs.
** varlen bytes (64,256, 1k ,4k, 16k? or more?), e.g. just cover large entries
case.
# Key-val pairs of simple object with single field:
** Same cases as above to verify the overhead? or may be just a part of them?
# Key-val pairs of complex multi-fields objects. Varlen fields should be short:
** with non-null fields (for ommited null map)
** with no varlen fields (with ommited offset table)
** fix-len non-null fields (minimal overhead).
** any fields.
It look like a large task, may be it make sense to implement few of them
especially there is no support for date-time, collection/arrays yet.
What framework can be used for this purpose? JMH or Jardstick? I doubt the last
one will be easier.

> Project: Ignite
> Issue Type: Improvement
> Components: sql
> Reporter: Alexey Goncharuk
> Assignee: Andrey Mashenkov
> Priority: Major
> Labels: iep-54, ignite-3
>
> 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.
