Anton Vinogradov commented on IGNITE-27606:
-------------------------------------------

I removed the {{wire-format}} label from this ticket.

That label marks the tickets that change the message format and therefore have 
to be merged before 2.19 is released. This change turned out to be 
wire-neutral: the {{byte[]}} and its byte layout are unchanged, only the way it 
is accessed. The label was added when the first reading of the ticket assumed 
the raw array would have to become typed fields.

The fixVersion stays 2.19, since that is the release the fix goes into.

> The current implementation of PartitionUpdateCountersMessage performs counter 
> transformations using raw arrays and GridUnsafe. Propose and implement an 
> alternative approach that avoids GridUnsafe and reduces low-level array 
> manipulation, without regressions in performance or network serialization 
> behavior
