Carl Boettiger commented on ARROW-8810:
---------------------------------------
Thanks all, this is a great answer. Would love to see some of these details
mentioned in the R vignettes, as no doubt other R users might also be unclear
how this differs from other compressed/encoded filetypes (e.g. the issue of
metadata in the file footer).
Writing multiple files makes sense for larger chunks. My current use case is
effectively streaming (currently just to .tsv.gz compressed table), so I'm
definitely following the discussion in ARROW-8784.
Please feel free to close, and thanks again for this fantastic library and the
R bindings.
> [R] Append to parquet file?

> Key: ARROW-8810
> URL: https://issues.apache.org/jira/browse/ARROW-8810
> Project: Apache Arrow
> Issue Type: Improvement
> Components: R
> Reporter: Carl Boettiger
> Priority: Major
>
> Is it possible to append new rows to an existing .parquet file using the R
> client's arrow::write_parquet(), in a manner similar to the `append=TRUE`
> argument in text-based output formats like write.table()?
>
> Apologies as this is perhaps more a question of documentation or user
> interface, or maybe just my ignorance.
