Thank you David. I have trouble building the
asset-transfer-ledger-queries chaincode in Go Lang (as I can see
that is not available in Java) so I can not see the result
structure of the data in the test-network. Nevertheless, I
understand that the GetHistoryForKey
function will return the entire chain of custody for an asset since
issuance and I have to then "crop" the desired range of dates.
I am still worried about the time it takes to retrieve all this information, as I will often write IoT measurements from multiple sensors to the ledger.
