When we create an rdd, does it bring the data and load it into the memory?

Question Posted / Apurav Garg

Answer Posted / Apurav Garg

No, creating an RDD in Apache Spark does not automatically load all the data into memory. By default, only part of the data is loaded into memory as needed to perform transformations or actions. If more data is required during computation, additional data can be fetched from storage.
