> Hi all,
> Apologises if this has already been covered by another ticket. Is it possible for arrow to read in compress delimited files (for example gzip)?
> Currently I get an error when trying to read in a compressed delimited file:
>  
> {code:java}
> vroom::vroom_write(iris, "iris.csv.gz", delim = ",")
> arrow::read_csv_arrow("iris.csv.gz")
> # Error in csv__TableReader_Read(self) :
> # Invalid: CSV parse error: Expected 1 columns, got 4{code}
> however it can be read in by vroom and readr:
> {code:java}
> vroom::vroom("iris.csv.gz")
> readr::read_csv("iris.csv.gz")
> {code}
>
