Documentation

Overview

Package models contain the key job components used by the Chainlink application.

Common

Common contains types and functions that are useful across the application. Particularly dealing with the URL field, dates, and time.

Eth

Eth creates transactions and tracks transaction attempts on the Ethereum blockchain.

JobSpec

A JobSpec is the largest unit of work that a Chainlink node can take on. It will have Initiators, which is how a JobRun is started from the job definition, and Tasks, which are the specific instructions for what work needs to be performed. The BridgeType is also located here, and is used to define the location (URL) of external adapters.

ORM

The ORM is the wrapper around the database. It gives a limited set of functions to allow for safe storing and withdrawing of information.

Run

A Run is the actual invocation of work being done on the Job and Task. This comprises of JobRuns and TaskRuns. A JobRun is like a workflow where the steps are the TaskRuns.

i.e. We have a Scheduler Initiator that creates a JobRun every monday based on a JobDefinition. And in turn, those JobRuns have TaskRuns based on the JobDefinition's TaskDefinitions.

var LogBasedChainlinkJobInitiators = []string{InitiatorRunLog, InitiatorEthLog, InitiatorRandomnessLog}

LogBasedChainlinkJobInitiators are initiators which kick off a user-specified chainlink job when an appropriate ethereum log is received. (InitiatorFluxMonitor kicks off work, but not a user-specified job.)

View Source 
var TopicsForInitiatorsWhichRequireJobSpecIDTopic = map[string][]common.Hash{
	InitiatorRunLog:        {RunLogTopic20190207withoutIndexes},
	InitiatorRandomnessLog: {RandomnessRequestLogTopic},
}

topicsForInitiatorsWhichRequireJobSpecTopic are the log topics which kick off a user job with the given type of initiator. If chainlink has any jobs with these initiators, it subscribes on startup to logs which match both these topics and some representation of the job spec ID.
