Hi, Reading though the latest documentation for Memory management I can see that the parameter spark.memory.offHeap.enabled (true by default) is described with ‘If true, Spark will attempt to use off-heap memory for certain operations’ [1].
Can you please describe the certain operations you are referring to? http://spark.apache.org/docs/latest/configuration.html#memory-management <http://spark.apache.org/docs/latest/configuration.html#memory-management> Thank! Best, Ovidiu
