Which statement describes the default execution mode for Databricks Auto Loader?

Show Suggested Answer Hide Answer
Suggested Answer: D

When triggering a job run using the Databricks CLI, the run_id field in the response represents a globally unique identifier for that particular run of the job. This run_id is distinct from the job_id. While the job_id identifies the job definition and is constant across all runs of that job, the run_id is unique to each execution and is used to track and query the status of that specific job run within the Databricks environment. This distinction allows users to manage and reference individual executions of a job directly.

D seems off too; it doesn't match the usual behavior.

I thought the default execution mode was about incrementally loading files, so I’m leaning towards A, but I need to double-check the details.

I vaguely recall something about webhooks, but I can't remember if that's the default mode or just an additional feature.

I remember practicing a question about Auto Loader, and I feel like it mentioned using cloud vendor-specific services, which makes me lean towards option B.

I'm pretty sure the answer is option A. The key details are that it identifies new files by listing the input directory and then loads them incrementally and idempotently into the target table. That sounds like the default behavior I'm familiar with for Databricks Auto Loader.

Based on my understanding, the default mode is option B. It uses cloud vendor-specific queue storage and notification services to track newly arriving files and then incrementally and impotently loads them into the target Delta Lake table.

Hmm, I'm a bit confused on this one. The options seem similar, but I'm not sure which one exactly describes the default behavior. I'll need to review the Databricks Auto Loader documentation more closely to be confident in my answer.

Webhook triggers and automatic merging of data sound cool, but that's probably not the default behavior for Databricks Auto Loader. I'm going with Option A.

I'm not sure about the difference between 'incrementally and idempotently' and 'incrementally and impotently'. That's a bit confusing, but I think Option A is still the best choice here.

I think 'incrementally and idempotently' means files are loaded without duplication, while 'incrementally and impotently' might be a typo.
