[jira] [Closed] (ARROW-12023) Allow for AsyncGenerator>

     [ https://issues.apache.org/jira/browse/ARROW-12023?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Weston Pace closed ARROW-12023.
-------------------------------
    Resolution: Invalid

This can already be done through a combination of `MakeSingleFutureGenerator` and `MakeMerged`/`MakeConcatenated`.  It is also no longer needed in the scanner.

> Sometimes it's useful to do something like...
> Collect(source.Map(x => table_builder.AddTable())
> For example, in Scanner::ToTableAsync the table_building_task returns std::shared_ptr because we need something "iterable" currently.
