In simple-clinet.cc example I have:
Scan scan{};
auto scanner = table->Scan(scan);
auto r = scanner->Next();
while (r != nullptr) {
Scan is from begin of table. How scan from specified row?
Scan scan{row__key_string} ?
But there are further problems: because row_key must be unique it often
is concatenation key1+key2+key3
Is possible start scan from key1+any_keys2and3 ?
