| \usage{ |
| read_ipc_stream(file, as_data_frame = TRUE, ...) |
| } |
| \arguments{ |
| \item{file}{A character file name or URI, \code{raw} vector, an Arrow input stream, |
| or a \code{FileSystem} with path (\code{SubTreeFileSystem}). |
| If a file name or URI, an Arrow \link{InputStream} will be opened and |
| closed when finished. If an input stream is provided, it will be left |
| open.} |
| |
| \item{as_data_frame}{Should the function return a \code{data.frame} (default) or |
| an Arrow \link{Table}?} |
| |
| \item{...}{extra parameters passed to \code{read_feather()}.} |
| } |
| \value{ |
| A \code{data.frame} if \code{as_data_frame} is \code{TRUE} (the default), or an |
| Arrow \link{Table} otherwise |

| \description{ |
| Apache Arrow defines two formats for \href{https://arrow.apache.org/docs/format/Columnar.html#serialization-and-interprocess-communication-ipc}{serializing data for interprocess communication (IPC)}: |
| a "stream" format and a "file" format, known as Feather. \code{read_ipc_stream()} |
| and \code{\link[=read_feather]{read_feather()}} read those formats, respectively. |
| } |
| \seealso{ |
| \code{\link[=write_feather]{write_feather()}} for writing IPC files. \link{RecordBatchReader} for a |
| lower-level interface. |
