Read from various data sources.
Shape and optimize for your needs.
Store and secure in one of many available data sinks.
Load all rows into memory and process them at once. This is useful for debugging and working with small datasets.
Warning: Avoid using collect with large datasets as it loads everything into memory. For controlled memory consumption, use batchSize instead.
