[jira] [Comment Edited] (IGNITE-13618) Provide generated and
reflection-based class (de)serializers
[ https://issues.apache.org/jira/browse/IGNITE-13618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17236408#comment-17236408 ]

I've pushed benchmark test "SerializerBenchmarkTest".
Please, note Reflection-based serialized is already optimized and uses Unsafe directly bypassing some reflection methods.
Still generated serializer shows noticeable better results.
PFA benchmark results attached.

> 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.
