Which of the following describes a partition?
A partition is a collection of rows of data that fit on a single machine in a cluster. In Spark, data is split into partitions for processing. Each partition can be considered a subset of the overall dataset that is distributed across different nodes in a cluster, enabling parallel processing and efficient computation. This partitioning allows Spark to break down large datasets and process them in smaller, manageable pieces across the cluster’s nodes.
It is B
I think it's E.
E. A partition is a collection of rows of data that fit on a single machine in a cluster. Explanation: In Spark, data is divided into partitions, which are distributed across the nodes in a cluster. Each partition holds a subset of the data, and operations in Spark are performed in parallel on these partitions. Partitions are the unit of parallelism in Spark, allowing computations to be distributed across multiple executor nodes efficiently.
