[jira] [Commented] (ARROW-15258) [C++] Easy options to create a source node from a table

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

    [ https://issues.apache.org/jira/browse/ARROW-15258?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17481577#comment-17481577 ] 

Vibhatha Lakmal Abeykoon commented on ARROW-15258:
--------------------------------------------------

[~westonpace] 

One straight forward way to provide this functionality is to use 

The `ScanNodeOptions` can be wrapped and create `TableSourceOptions` 

Reasoning: When creating from existing table, user may need to filter, select columns, etc as options. And also we can add other options required for this operation too. 

Table -> InMemoryDataset -> Scan(table, options)

Any thoughts on this.

> Given a Table there should be a very simple way to create a source node.  Something like:
> {code}
>   std::shared_ptr<Table> table = ...
>   ARROW_RETURN_NOT_OK(arrow::compute::MakeExecNode(
>       "table", plan, {}, arrow::compute::TableSourceOptions{table.get()}));
> {code}
