[jira] [Commented] (ARROW-15262) [C++] Create a ToTable sink node

["Vibhatha Lakmal Abeykoon (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-15262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17482886#comment-17482886 ] 

Vibhatha Lakmal Abeykoon commented on ARROW-15262:
--------------------------------------------------

For this one tested an approach by considering an extension to the `consuming_sink`. Since we want to provide the output from the exec system to an outside system or resume outside the exec-plan, this could be sufficient. 

[~westonpace] any thoughts?

> The invocation would look something like:

>   std::shared_ptr<Table> out_table;
>   ARROW_RETURN_NOT_OK(arrow::compute::MakeExecNode(
>       "table_sink", plan, {terminal_node}, arrow::compute::TableSinkOptions{&out_table}));
> {code}
> When the plan is finished (assuming a successful finish) then {{out_table}} will be the output of the plan collected into a table.  The schema of the table will be {{terminal_node->output_schema()}}
