Temporary Shorcut For Reading Arrow/Parquet Bit Into R via ‘reticulate’
Description
Work is being done to make Parquet/Arrow a first-class R citizen but – until then – I don’t always want a Drill server round trip just to read in some data and same goes for firing up a Spark instance (srsly). So, this is a quick hack until the R packages are done.
NOTE
Requires Python 3.5+, pyarrow and pandas.
What’s Inside The Tin
The following functions are implemented:
read_parquet: Read in data from Parquet into an R data frame via ‘reticulate’
