For any queries/reporting beyond simple JSON queries, the recommendation is to use a downstream purpose-built data service. Chaincode is optimized for transactions, not large queries. See an example o

#couchdb #fabric #hyperledger-fabric

The query appears to be a JSON find query. These queries will be slow or time out if they do not utilize a well designed index against the JSON data. See the CouchDB tutorial for more details: https:/

Yes, I have tried that. The CouchDB volumes were removed properly. But even if not, when the Docker containers are removed and re-created - somehow it should be populated (again) if I do the same step

Hi! I was testing out the database capabilities and effects on changes in the fabric-samples. (fabcar) In a trial run I've removed all databases and all data from both couchdb-Docker instances. Everyt

The second version of the chaincode would have to support both the old and new data. There are various approaches possible: You could attempt to unmarshal the JSON using new data structure, and if it

What should I search for in the peer logs? Some sort of error? Because I can't see the index on the couchdb entries
