@pmak-852 Spark is the distributed processing engine for big data. When processing small data with multiple cores, it will be dividing the data frame into multiple partitions equal to number of cores. Spark have its overhead to start executor and communicate between two tasks. That's why when processing with 1 core may be faster compared to multiple cores as the actual data processing time is very less compared to other spark overheads. -- This is an automated message from the Apache Git Service.
