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. -- This message was sent by Atlassian JIRA (v7.6.14#76016)
