Joris Van den Bossche commented on ARROW-3391:
----------------------------------------------
[~uwe] What kind of wrong results do you expect?
I am testing this with the new Datasets API, where we do not have this check
for {{\0}}, but I also don't directly see wrong behaviour (eg when filtering on
equality with {{"a\0"}} correctly gives an empty table when the partition
values are "a" and "b")
> [Python] Support \0 characters in binary Parquet predicate values
> -----------------------------------------------------------------

> Key: ARROW-3391
> URL: https://issues.apache.org/jira/browse/ARROW-3391
> Project: Apache Arrow
> Issue Type: Improvement
> Components: Python
> Reporter: Uwe Korn
> Priority: Major
> Labels: dataset, parquet
>
> As we convert the predicate values of a Parquet filter in some intermediate
> steps to C-style strings, we currently disallow the use of binary and string
> predicate values that contain {{\0}} bytes as they would otherwise result in
> wrong results.
