What is the generic Input component used for in a Joblet design?

Show Suggested Answer Hide Answer
Suggested Answer: C

The generic Input component used for in a Joblet design is the tJobletInput component. This component is used to carry data into a Joblet from another component in the job that contains the Joblet. A Joblet is a reusable piece of a job that can be used in multiple jobs as a single component. A Joblet can have one or more input and output flows that connect it with other components in a job. To create these flows, you need to use generic input and output components, such as tJobletInput, tJobletOutput, tJobletTriggerInput, and tJobletTriggerOutput. These components allow you to define schemas and triggers for your Joblet without depending on specific components.

The tJobletInput component is not used for triggering a Joblet, triggering a subjob, or carrying data into a subjob. These are different concepts and functionalities in Talend Studio. A trigger is a link that activates a subjob or a component based on a condition or an event. A subjob is a part of a job that consists of one or more components connected by data flows or triggers. A subjob can be triggered by another subjob using triggers such as OnSubjobOk, OnSubjobError, Run if, etc. A subjob can also carry data into another subjob using data flows such as main, lookup, reject, etc.Reference:Talend Open Studio: Open-source ETL and Free Data Integration | Talend, [tJobletInput properties - 7.3], [Joblets - 7.3], [Triggers - 7.3]

I thought the Input component was specifically for triggering a subJob, but now I'm second-guessing myself after reviewing the material.

I feel like the Input component is used for carrying data, but I might be mixing it up with something else.

I remember practicing a question about Joblets, and I think the Input component was related to triggering something, but I can't recall if it was a Joblet or a subJob.

I think the Input component is mainly about carrying data into a Joblet, but I'm not completely sure.

Okay, I think the key here is that the Input component is used to bring data into a Joblet, not a subJob. So I'm going to go with option C.

I remember learning about Joblets and subJobs, but I'm not confident I fully understand the difference. I'll have to make an educated guess on this one.

I was stuck between B and C, but C makes more sense. Triggering a subJob is a different functionality altogether.

I agree with Sunshine. If you're designing a Joblet, you'd want to use the Input component to bring in the necessary data, not to trigger anything.
