Neal Richardson updated ARROW-6278:
-----------------------------------
Description:
{{read_parquet}} currently handles a path to a local file or an Arrow input
stream. Would it be possible to add support for a raw vector containing the
contents of a parquet file?
Apologies if there is already a way to do this. I have tried populating a
buffer and passing that as input, but that is unsupported as well. An example
of how to work using an input stream would be useful as well.
was:
(See original question below and discussion; this was originally about reading
{{raw}} class data as a Parquet file, but that was a need arising out of the
lack of HDFS support.)
