I agree that this is probably the OP's "question".

However, as C++ and Ada have quite similar programming and computation 
models, it is highly likely that an Ada implementation of the ScyllaDB 
design can be made to have similar performance (within small constant 
factors) as the C++ implementation.

It is less certain that the ScyllaDB design can be expressed as nicely 
(where nicely = directly, readably, compactly, maintainably, etc.) in 
Ada source code as in C++ source code.
