Hyperledger Invoker Component

This component connects to a Hyperledger Peer channel, invokes a chaincode smart contract specified in its configuration, and outputs the result of that invocation.

Data Governance

The Hyperledger Component does not perform any Data Governance operations.

Input Channels

execute — When a SignalData object is received on this channel, invokes the configured smart contract function with the configured parameters (unless it is already being executed, in which case the signal is discarded and a message is added to the deployment audit logs).

Output Channels

default — Outputs a StringData object containing the result of the smart contract invocation.

error — Outputs an ErrorOutput object if there is an error executing the query.

Parameters

chaincodeName — (String) The name of the chaincode smart contract to invoke.

chaincodeFunction — (String) The name of the chaincode smart contract function to be invoked.  

chaincodeFunctionParams — (String) A CSV containing 0 or more items which are the parameters to be passed into the function.

executeOnStart — (Boolean, default: true) Specifies whether the component should the smart contract be invoked as soon as the pipeline starts.
