Explain partitions?

Question Posted / Rajeev Kumar Gangwar

Answer Posted / Rajeev Kumar Gangwar

"Partitions are a way to divide data into smaller, independent chunks for efficient parallel processing in Apache Spark. Each partition is an ordered sequence of records and they are processed independently by different worker nodes in a cluster. The number of partitions can be set while creating RDDs or DataFrames/DataSets and it directly impacts the degree of parallelism during execution."
