* * Based on the closedRight and stampRight parameters, resampling partitions time into non- Resample equivalent in pysaprk is groupby + window : grouped = df.groupBy('store_product_id', window("time_create", "1 day")).agg(sum("Production").alias('Sum Production')) here groupby store_product_id , resample in day and calculate sum. Group by and find first or last: refer to https://stackoverflow.com/a/35226857/1637673 For example, the elements of RDD1 are (Spark, Spark, Hadoop, Flink) and that of RDD2 are (Big data, Spark, Flink) so the resultant rdd1.union(rdd2) will have elements (Spark, Spark, Spark, Hadoop, Flink, Flink, Big data). Union() example: [php]val rdd1 = spark.sparkContext.parallelize(Seq((1,”jan”,2016),(3,”nov”,2014),(16,”feb”,2014))) PySpark sampling ( pyspark.sql.DataFrame.sample ()) is a mechanism to get random sample records from the dataset, this is helpful when you have a larger dataset and wanted to analyze/test a subset of the data for example 10% of the original file. Below is syntax of the sample () function.
