[GitHub] [arrow-datafusion] alamb opened a new pull request, #6736: Docs: Update SQL status page

alamb opened a new pull request, #6736:
URL: https://github.com/apache/arrow-datafusion/pull/6736

   # Which issue does this PR close?
   
   re #3058 
   
   # Rationale for this change
   
   Someone internally at InfluxData was referring to the SQL status page in DataFusion and since it was out of date it was confusing
   
   # What changes are included in this PR?
   
   Update the SQL status page  -- I also removed several lists of functions that had their own documentation page rather than trying to keep two lists up to date
   
   # Are these changes tested?
   N/A
   
   # Are there any user-facing changes?
   Better docs
   
   <!--
   If there are user-facing changes then we may require documentation to be updated before approving the PR.
   -->
   
   <!--
   If there are any breaking changes to public APIs, please add the `api change` label.
   -->

Review Comment:
   Yes, you are right that the support is only partial - I'll see if I can find some way to make this clearer

Review Comment:
   I think good JSON support is very important to get Datafusion more traction in the general community. SQL2023 has some good stuff about this (see [here for a good summary](http://peter.eisentraut.org/blog/2023/04/04/sql-2023-is-finished-here-is-whats-new).).
   
   [This DuckDB page](https://duckdb.org/2022/05/04/friendlier-sql.html) is also a good list of desiderata for us (some of these we implemented already).
   
   I plan to actively talk about/promote Datafusion in various venues once we get into a state where these things "just work".

Review Comment:
   Sorry @alamb that is not very clear to me.
   Do you mean DF supports SQL syntax to insert data into CSV file?

Review Comment:
   I think good JSON support is very important for Datafusion to get more traction in the general community. SQL2023 has some good stuff about this (see [here for a good summary](http://peter.eisentraut.org/blog/2023/04/04/sql-2023-is-finished-here-is-whats-new).).
   
   While we are on the SQL support/ease-of-use topic, [this DuckDB page](https://duckdb.org/2022/05/04/friendlier-sql.html) is also a good list of desiderata for us (some of these we implemented already).
   
   I plan to actively talk about/promote Datafusion in various venues once we get into a state where these things "just work".

Review Comment:
   > I think good JSON support is very important for Datafusion to get more traction in the general community. SQL2023 has some good stuff about this (see here for a good summary.).
   
   I agree.

    It would be great to file tickets about these features -- I have found clearly written tickets with a "good first issue" often attracts contributions. If you have a chance to file the tickets that would be awesome, otherwise I will try and find time to do so
   
   
   > I plan to actively talk about/promote Datafusion in various venues once we get into a state where these things "just work".
   
   I think it is a balance -- part of the way we grow the DataFusion community (to get the resources to make it better) is to talk about it publically.

Review Comment:
   I think good JSON support is very important for Datafusion to get more traction in the general community. SQL2023 has some good stuff about this (see [here for a good summary](http://peter.eisentraut.org/blog/2023/04/04/sql-2023-is-finished-here-is-whats-new).).
   
   [This DuckDB page](https://duckdb.org/2022/05/04/friendlier-sql.html) is also a good list of desiderata for us (some of these we implemented already).
   
   I plan to actively talk about/promote Datafusion in various venues once we get into a state where these things "just work".

Review Comment:
   ❤️  -- I also think https://github.com/apache/arrow-datafusion/issues/5654 is very related (rather than having to define the table in order to add to it). See #6539 where I started the basics

Review Comment:
   Yes, that is correct Here is an example:
   
   ```shell
   (arrow_dev) alamb@MacBook-Pro-8:~/Software/arrow-site$ touch /tmp/foo.csv
   (arrow_dev) alamb@MacBook-Pro-8:~/Software/arrow-site$ datafusion-cli
   DataFusion CLI v26.0.0
   ❯ create external table foo (x int) stored as csv location '/tmp/foo.csv';
   0 rows in set. Query took 0.004 seconds.
   ❯ insert into foo values (1), (2), (3);
   +-------+
   | count |
   +-------+
   | 3     |
   +-------+
   1 row in set. Query took 0.005 seconds.
   ❯
   \q
   (arrow_dev) alamb@MacBook-Pro-8:~/Software/arrow-site$ cat /tmp/foo.csv
   1
   2
   3
   ```
   
   The UX is somewhat awkward at the moment as it can only append into existing files (not create new ones). I have real hopes it will be improved
