I have been working on Hyperledger Fabric for the last 6 months on different kind of projects. In my last project I would like to integrate a database for saving XML file. Two possibilities, either IPFS style DB or general DB style like NoSQL.
For IPFS It would be pretty easy to integrate from the frontend and save the hash to the ledger, but I don’t need a decentralized DB. My choice then goes to a centralized DB like NoSQL.
For NoSQL, I identified two choices :
Drawback identified on solution 1):
Drawback identified on solution 2)
There is probably lots of more error-prone possibilities. But I would be really interested to know if anyone already implemented some kind of similar solution.
