rquery and rqdatatable,: R tools for Rapid Data Manipulation

In this talk John Mount of Win-Vector, LLC will demonstrate the CRAN package rquery, and the new package rqdatatable.

rquery is a query generator for R based on Edgar F. Codd's relational algebra, and on production experience using SQL and dplyr at big data scale. rquery is powerful, easy to teach, has error checking, and basic query optimization. It is the fastest way to manipulate remote big data from R, for example data found on PostgreSQL or Spark. rqdatatable is a new package that implements the rquery grammar in memory using the data.table package. This allows the same rquery pipeline to be used remotely. such as on Spark, and for in-memory data. rqdatatable transforms are usually nearly as fast as native data.table code and usually much faster than the equivalent base-R or dplyr code.

These packages can save substantial development and infrastructure costs.
