Project Zen initiative Project Zen was initiated in this release to improve PySpark’s usability in the following manner: Being Pythonic Pandas UDF enhancements and type hints Avoid dynamic function definitions, for example, at funcitons.py which makes IDEs unable to detect. Better and...

In the example below, we can usePySparkto run an aggregation: PySpark df.groupBy(df.item.string).sum().show() In the example below, we can usePySQLto run another aggregation: PySQL df.createOrReplaceTempView("Pizza") sql_results = spark.sql("SELECT sum(price.float64),count(*) FROM ...
What is Scriptis? Scriptis is for interactive data analysis with script development(SQL, Pyspark, HiveQL), task submission(Spark, Hive), UDF, function, resource management and intelligent diagnosis. Scriptis AppJoint integrates the data development capabilities of Scriptis to DSS, and allows various ...
