YAWNDB was never supposed to be a general-purpose DB. Instead, it was a relatively quick hack to store data that fits in memory and is frequently updated. This is why there is no proper migration (or there was, I hope Pavel will correct me if they added migration lately) and larger-than-memory dataset support.

It's also worth noting that there were no OpenTSDB or InfluxDB on the horizon when YAWNDB was hacked together. They are way more powerful and flexible than YAWNDB, but also more complex.
