Understanding the various triggers in ADF is crucial for managing data workflows effectively.
Discuss the types of triggers such as schedule triggers, tumbling window triggers, and event-based triggers, and provide examples of when you would use each.
“There are three main types of triggers in ADF: schedule triggers, which run pipelines at specified intervals; tumbling window triggers, which allow for more complex scheduling; and event-based triggers, which respond to events in Azure Blob Storage. For instance, I used an event-based trigger to initiate a data pipeline whenever new data was uploaded to a blob container, ensuring timely processing.”
This question assesses your troubleshooting and optimization skills in a cloud-based data environment.
Explain your approach to identifying performance bottlenecks, such as analyzing execution plans, and discuss techniques for optimizing Spark jobs.
“To diagnose issues in Databricks, I would start by reviewing the Spark UI to identify stages that are taking longer than expected. I often optimize code by caching intermediate results, using broadcast variables for smaller datasets, and ensuring that data is partitioned correctly to minimize shuffling.”
This question evaluates your hands-on experience with ETL tools and methodologies.
Mention specific ETL tools you have used, your role in the ETL process, and any challenges you faced.
“I have extensive experience with Azure Data Factory for building ETL pipelines.
