नमूना प्रश्न
अभ्यास कैसे काम करता है, यह जानने के लिए एक उत्तर चुनें और व्याख्या देखें।
A developer needs to write DataFrame orders to a Parquet path, overwrite existing data, and physically partition the output by country for later pruning. Which PySpark write pattern is correct?
A claims enrichment pipeline groups 420 GB by policy_id. The team changed spark.sql.shuffle.partitions from 200 to 24 to reduce small files, and now several reducers run much longer than the rest. What does this setting control?
A team creates a persistent Spark SQL table for orders and frequently filters by country while ordering recent rows by ingestion time inside each partition. Which approach best supports retrieval without changing query semantics?
A notebook creates two SparkSession objects for a claims enrichment experiment, each with a different warehouse directory. The second object appears to reuse the same application and catalog state. Which explanation is most accurate?
A CSV-based orders ingestion job uses Spark SQL and occasionally receives rows with embedded delimiters and malformed records. Which direction is most defensible before querying the data?
