What is driver memory and executor memory in spark?

Question Posted / Dharmendra Yadav

Answer Posted / Dharmendra Yadav

"Driver memory" refers to the amount of RAM allocated for the Spark application's driver program, which manages tasks and data distribution. On the other hand, "Executor memory" denotes the memory available to each worker node (executor) that processes tasks concurrently in a Spark cluster. This memory is used to store intermediate results and cached data.n
