How do I read a Parquet in R and convert it to an R DataFrame?

Question

I\'d like to process Apache Parquet files (in my case, generated in Spark) in the R programming language.

Is an R reader available? Or is work being done on one?

Answer 1

If you have a multi-file parquet file, you might need to do something like this :

data.table::rbindlist(lapply(Sys.glob("path_to_parquet/part-*.parquet"), arrow::read_parquet))
