Read a Feather file (an Arrow IPC file)Source:
Feather provides binary columnar serialization for data frames.
It is designed to make reading and writing data frames efficient,
and to make sharing data across data analysis languages easy.
read_feather() can read both the Feather Version 1 (V1), a legacy version available starting in 2016,
and the Version 2 (V2), which is the Apache Arrow IPC file format.
read_ipc_file() is an alias of
read_feather(file, col_select = NULL, as_data_frame = TRUE, mmap = TRUE) read_ipc_file(file, col_select = NULL, as_data_frame = TRUE, mmap = TRUE)
A character file name or URI,
rawvector, an Arrow input stream, or a
FileSystemwith path (
SubTreeFileSystem). If a file name or URI, an Arrow InputStream will be opened and closed when finished. If an input stream is provided, it will be left open.
Should the function return a
tibble(default) or an Arrow Table?
Logical: whether to memory-map the file (default
TRUE (the default), or an
Arrow Table otherwise
