> Please be gentle! :)
> As a heavy R user that normally interacts with parquet files using SparklyR,
> I have recently decided to try to use arrow::read_parquet() on a few parquet
> files that were on my local machine rather than in hadoop. I was not able to
> proceed after several various attempts due to embedded nuls. For example:
> try({df <- read_parquet('out_2019-09_data_1.snappy.parquet') })
> Error in Table__to_dataframe(x, use_threads = option_use_threads()) :
> embedded nul in string: 'INSTALL BOTH LEFT FRONT AND RIGHT FRONT TORQUE
> ARMS\0 ARMS'
> Is there a solution to this?
> I have also hit roadblocks with embedded nuls in the past with csvs using
> data.table::fread(), but readr::read_delim() seems to handle them gracefully
> with just a warning after proceeding.
> Apologies that I do not have a handy reprex. I don't know if I can even
> recreate a parquet file with embedded nuls using arrow if it won't let me
> read one in, and I can't share this file due to company restrictions.
> Please let me know how I can be of any more help!
