In contrast with base R functions, RevoScaleR operations can be performed against very large datasets, in parallel, and on distributed file systems. Functions can operate over datasets that do not fit in memory by using chunking and by reassembling results when operations are complete.

RevoScaleR serves as a platform for distributed data science. For example, you can use the RevoScaleR compute contexts and transformations with the state-of-the-art algorithms in [MicrosoftML](https://docs.microsoft.com/machine-learning-server/r/concept-what-is-the-microsoftml-package). You can also use [rxExec](https://docs.microsoft.com/machine-learning-server/r-reference/revoscaler/rxexec) to run base R functions in parallel.
