-------------------------------------------
Result do not prove that this change makes sense. Closing the ticket.
> String marshalling can be optimized for binary marshaller

> Issue Type: Task
> Components: binary
> Reporter: Yakov Zhdanov
> Assignee: Vadim Opolski
>
> Currently string serialization is done in two steps (see
> {{BinaryWriterExImpl#doWriteString}}):
> {code}
> strArr = BinaryUtils.strToUtf8Bytes(val); // Encode string into byte array.
> out.writeByteArray(strArr); // Write byte array into stream.
> {code}
> Probably we can write directly into stream while string is encoded, without
> intermediate array. This both reduces memory consumption and eliminates array
> copy step.
> Need to create a micro benchmark first to check if it gives any improvement.
