Apache Arrow defines two formats for serializing data for interprocess communication (IPC):
a "stream" format and a "file" format, known as Feather. write_ipc_stream()
and write_feather()
write those formats, respectively.
write_arrow(x, sink, ...)
write_ipc_stream(x, sink, ...)
data.frame
, RecordBatch, or Table
A string file path, URI, or OutputStream, or path in a file
system (SubTreeFileSystem
)
extra parameters passed to write_feather()
.
x
, invisibly.
write_arrow()
, a wrapper around write_ipc_stream()
and write_feather()
with some nonstandard behavior, is deprecated. You should explicitly choose
the function that will write the desired IPC format (stream or file) since
either can be written to a file or OutputStream
.
write_feather()
for writing IPC files. write_to_raw()
to
serialize data to a buffer.
RecordBatchWriter for a lower-level interface.
