Hi, I'm wondering how far off base I am with the question:
Is a LogicalPlan in #SparkSQL similar to a RDD in #ApacheSpark Core in that they both seem a metadata of the computation that eventually gets executed to produce records? What am I missing if anything? How imprecise I am by comparing LogicalPlan to RDD? I'm considering a Dataset a pair of a LogicalPlan and an Encoder where the encoder is to handle the data in a more sophisticated, low-level way while LogicalPlan is how the data is computed/retrieved. Please help me understand the concepts in a more accurate way. Thanks!
