Hyperledger Fabric Average Max Price FabCar

0 votes
Hey,

I'm using the fabcar project  (https://github.com/IBM/blockchain-application-using-fabric-java-sdk).

I added a price attribute and I would like to obtain statistics like the average or maximum price of the cars stored.

Is there any Go function to do so?

Thank you very much.

Hey, @pablobnet,

You can use GetHistoryForKey() to retrieve all the cars. Then, calculate the average price ciclying on them.
