Show Suggested 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.

Directory querying all valid files? That sounds like a lot of work. I'm going to have to go with Option A on this one.

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.

User 2: Yeah, I agree. It makes sense that new files are incrementally loaded into the target Delta Lake table.

Option A seems like the correct default execution mode for Databricks Auto Loader. It makes sense that it would identify new files by listing the input directory and load them incrementally and idempotently into the target Delta Lake table.
