Default Number Of Partitions In Spark at Justin Hoysted blog

Default Number Of Partitions In Spark. Val rdd1 = sc.parallelize(1 to 10) println(rdd1.getnumpartitions) // ==> result is. What is the default number of spark partitions and how can it be configured? Let's start with some basic default and desired spark configuration parameters. There is no default partitioning logic applied. I am trying to see the number of partitions that spark is creating by default. When spark reads data from a distributed storage system like hdfs or s3, it typically creates a partition for each block of data. The default number of spark partitions can vary depending on the mode and environment, such as local. Default spark shuffle partitions — 200; A dataframe is partitioned dependent on the number of tasks that run to create it. When you read data from a source (e.g., a text file, a csv file, or a parquet file), spark automatically creates partitions based on the file blocks.
