Re: Caliper leveldb query error

  1. If you need rich queries for your tests, then you have to switch to CouchDB, meaning you have to configure every affected peer (that will run your chaincode) to use CouchDB.
  2. If you don’t need rich queries, then modify your chaincode to use standard/basic state DB operations.

 

All in all, if you want to use an existing chaincode that uses rich queries, then option 1) is the way to go. It’s not a big change to the peer configuration, so the amount of work needed is proportional to the number of peers you have.

Thanks for your reply.

Is there any way to fix this for levelDB, because all my testing are based on this, like changing the function by myself  or its complicated and time consuming?

 

Thanks

Hi George,

 

If the chaincode uses the "getQueryResult" chaincode stub method to perform a rich query, then the underlying world state DB must support this. Currently, this means you have to use CouchDB, independently of the Fabric version you use.

Tárgy: [Hyperledger Caliper] Caliper leveldb query error

 

Hello

My name is George and Im a student from Greece. During the benchmark on caliper i get these errors:

- Proposal response error by peer0.org1.example.com: GET_QUERY_RESULT

failed: transaction ID:

c3f8001687ffb79f411a29510a573ff77da6237645d808ed2e395490880ba1ee:

ExecuteQuery not supported for leveldb

 

Is there any way to fix this for leveldb or do I have to switch to couchdb?The version that im running is v1.4

 

Thanks in advance
