[Joris Van den Bossche](https://issues.apache.org/jira/browse/ARROW-12099?focusedCommentId=17312346) / @jorisvandenbossche: `[~malthe]` can you show small example input/output of what you imagine? (as has been clear above, describing it in words doesn't seem sufficient to...
[Joris Van den Bossche](https://issues.apache.org/jira/browse/ARROW-12099?focusedCommentId=17312363) / @jorisvandenbossche: I _assume_ your example starts with a table like the following? ```Java In [100]: table = pa.table({'a': [0, 1, 2], 'b': [[4, 5, 6]]*3})...
[Ian Cook](https://issues.apache.org/jira/browse/ARROW-12099?focusedCommentId=17405371) / @ianmcook: +1 Hive also has an [`explode`](https://cwiki.apache.org/confluence/display/hive/languagemanual+udf#LanguageManualUDF-explode) function that works like this, but it is very difficult to use at a table level—you need to use something...

[Guido Muscioni](https://issues.apache.org/jira/browse/ARROW-12099?focusedCommentId=17541192): (sorry for continuing this old thread, I can open a new issue if necessary) I was working on @jorisvandenbossche implementation and noticed that it skips the null values....
[Nick Crews](https://issues.apache.org/jira/browse/ARROW-12099?focusedCommentId=17555329): Small tweak to Guido's implementation (thank you for this!): If the table only has the one ListArray or MapArray column, then it crashes. This handles that case: ```python...

Can you change the .tar.gz file into a patch? EG see here: http://wiki.apache.org/lucene-java/HowToContribute. I think a good place for AESDirectory to...
