D69 DataFrames > RDDs for 95% of workloads. But RDDs make you understand Spark. Both matter. #ApacheSpark #BigData #SparkSQL #DataEngineering #ETL #PySpark #DataScience #MachineLearning #CloudComputing #Databricks #DistributedComputing
D52 Spark’s Catalyst Optimizer = SQL on steroids🧠 Rewrites queries→minimizes shuffles→maximizes performance. Invisible magic under the hood. #ApacheSpark #BigData #SparkSQL #DataEngineering #Databricks #ETL #DataPipeline #PerformanceOptimization #DataEngineer #PySpark #Cloud
D45 Spark SQL magic🪄 You can write: df.createOrReplaceTempView("sales") then run pure SQL: SELECT region, SUM(revenue) FROM sales GROUP BY region #SparkSQL #ApacheSpark #BigData #ETL #DataEngineering #Kafka #Streaming #BigData #DataEngineering #PySpark #DataScience #DataPipeline
Day 46 of my #buildinginpublic journey into Data Engineering Learned how to combine SQL + PySpark for large-scale analytics Created RDDs Ran SQL queries on DataFrames Performed complex aggregations Used broadcasting for optimization of joins #PySpark #SparkSQL #BigData
Use regex in Spark SQL for super-powerful string processing! With the RLIKE or REGEXP_EXTRACT functions, you can: Validate formats (e.g., emails, dates). Extract specific data (e.g., codes, values). Filter complex rows. Example: WHERE column RLIKE 'pattern' #SparkSQL
QUALIFY clause in Spark SQL filters the results of window functions (like RANK(), ROW_NUMBER()) without requiring subqueries. It acts like a HAVING clause specifically for window functions,simplifying your queries.QUALIFY RANK() = 1 to get the first record in each group.#SparkSQL
