Using kafka configuration in hyperledger composer

问题:

I just want to know whether we can use hyperledger composer in the scenario where there are multiple orderers deployed in kafka configuration ?

回答1:

Hyperledger Composer can be used against any fabric network setup. So it will work with both a Solo Orderer setup as well as a kafka configured setup. However as noted in the comment there is a limitation in that although you can define multiple orderers in the connection profile, only the first one in the list is used to interact with an orderer.

A new feature that went into the fabric-node-sdk 1.2 allows it to try other orderers in the list if it fails to send proposals to an orderer. When Composer is able to work with a fabric 1.2 setup then this feature will be available.
