B. Disabling Spark's adaptive query execution
C. Converting the DataFrame to RDD for Iceberg writes
D. Using the Z-Order clustering option in Iceberg
E. Filtering data as early as possible in the Spark transformation pipeline

Answer: A,D,E

Explanation:
A). Repartitioning can help distribute the write workload and improve parallelism. B. Z-Order clustering co-locates related data for faster filtering, improving query performance. C. Filtering early reduces the amount of data processed and written significantly. D. Adaptive query execution can sometimes make incorrect optimizations; disabling it may help in specific scenarios. E. RDDs offer less flexibility and are generally slower than DataFrames for Iceberg. CDP Iceberg

NEW QUESTION # 186
You need to optimize the performance of a Spark query that involves joining data from multiple Hive tables. What strategies can you employ to improve efficiency?

A. Use broadcast joins for small tables involved in the join operation
B. Pre-partition tables based on the join columns for faster data co-location
C. Increase the number of Spark executors without any further optimization
D. All of the above

Answer: D

Explanation:
A combination of strategies can significantly improve join performance. Increasing executors A can help, but it's not the sole solution. Broadcasting small tables B minimizes data movement. Pre-partitioning C ensures relevant data is on the same nodes, reducing network overhead. Combining these techniques provides the most optimal approach.

NEW QUESTION # 187

In Apache Spark, which storage level is recommended for caching data that is accessed frequently but is too large to fit in memory?

A. OFF HEAP
B. DISK ONLY
C. MEMORY AND DISK
D. MEMORY ONLY

Answer: C

Explanation:
The MEMORY_AND_DISK storage level is recommended for caching data that is frequently accessed but too large to fit entirely in memory. This level stores the data in memory as much as possible and spills the remainder to disk, providing a good balance between performance and resource utilization.

NEW QUESTION # 189
You have an Airflow DAG that extracts data from a CSV file. How can you ensure that the DAG doesn't attempt to process the same file multiple times in case of retries or task failures?

A. Implement a custom mechanism to rename the processed file after each successful run.
B. Use the File lock operator before the extraction task to prevent other tasks from accessing the file while it's being processed.
C. Modify the extraction task to skip processing existing files based on a timestamp or marker within the file.
D. Configure the DAG to run only once and manually trigger subsequent runs when needed.

Answer: B

Explanation:
The File lock operator is specifically designed to prevent concurrent access to a file during Airflow DAG execution. Option A ensures that only one task can process the CSV file at a time, preventing duplicate processing in case of retries or failures.
