Sparkr Distributed Data Processing With R Language Bindings

Unified engine for large-scale data processing and ML.

Unique: Translates dplyr-like R operations to Spark SQL logical plans with Arrow serialization for efficient data transfer; R UDFs execute in R processes on executors with automatic serialization/deserialization

vs others: More scalable than single-machine R for large datasets; more integrated than external R packages because operations execute on Spark cluster
