Brendan Hogan commented on ARROW-6278:
--------------------------------------
Fair question. I have parquet files in HDFS. I can, of course, open a spark
session and {{spark_read_parquet}}, but I am exploring options for
lighter-weight read access. I can grab the data into a raw vector via WebHDFS
(e.g. [https://mitre.github.io/webhdfs/]). Hence my interest in
{{read_parquet}} on that. I'm open to other suggestions here.
> [R] Handle raw vector from read_parquet
> ----------------------------------------

> Key: ARROW-6278
> URL: https://issues.apache.org/jira/browse/ARROW-6278
> Project: Apache Arrow
> Issue Type: New Feature
> Components: R
> Reporter: Brendan Hogan
> Priority: Major
>
> {{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.
