--------------------------------------------

Local benchmark result:
Benchmark                  (clusterSize)  (fsync)  (useSyncOptimization)  Mode  
Cnt   Score   Error  Units
SelectBenchmark.kvThinGet              1    false                   true  avgt  
 20  86,590 ± 2,708  us/op
SelectBenchmark.kvThinGet              1    false                  false  avgt  
 20  94,047 ± 0,979  us/op

The useSyncOptimization is a flag to apply this optimization or not. Based on 
this measurement, the optimization gives about an 8% reduction in latency.

> h3. Motivation
> In synchronous operation, we return the result to the fork join pool before 
> providing the result to the client in their pool. Of course, the tric costs 
> several microseconds.

> The issue is simullar IGNITE-22838 but about that type of operation that 
> started on the client side.
> h3. Definition of done
> We need to develop a strategy that does not involve the extra thread in 
> synchronous operation.
