BigData / Apache StreamPark Interview questions
When would you choose StreamPark over writing raw Flink CLI submission scripts?
Raw flink run scripts work fine for a single developer running a handful of jobs, but they stop scaling once more people, more jobs, or more operational rigor enter the picture.
StreamPark earns its keep once you need any of: a shared view of every job's status across a team, click-button savepoints instead of remembering CLI flags, consistent alerting when a job dies instead of someone noticing hours later, role-based access so not everyone can touch production jobs, or a repeatable build pipeline instead of "however that one engineer built it locally." It also removes the need to track, by hand, which script matches which running job's execution mode, Flink version, and parameters.
For a solo prototype or a one-off batch script, raw CLI submission is still simpler. StreamPark's value shows up as team size, job count, and production stakes grow.
