Hi,

I want to make jenkins pipeline job

to run whenever commit comes.

In checkout code, there's filter: [incremental(true)] feature like below.

checkout perforce(
    credential: 'p4',
    filter: [incremental(true)],
    populate: syncOnly(...),
    workspace: templateSpec(...)
)

What is this for? 

and there's polling build filters options in configuration page.

What is this for?

What is different with upper code ?

Many thanks,
