read_json_arrow(file, col_select = NULL, as_data_frame = TRUE, ...)



A character file name, raw vector, or an Arrow input stream. If a file name, a memory-mapped Arrow InputStream will be opened and closed when finished; compression will be detected from the file extension and handled automatically. If an input stream is provided, it will be left open.


A character vector of column names to keep, as in the "select" argument to data.table::fread(), or a tidy selection specification of columns, as used in dplyr::select().


Should the function return a data.frame (default) or an Arrow Table?


Additional options, passed to json_table_reader()


A data.frame, or an Table if as_data_frame = FALSE.
