   Hi @hi-rustin 
   
   There is some more detail here https://github.com/apache/arrow-datafusion/pull/2521#issuecomment-1135736282
   
   Here are some queries and examples that should work
   
   Given this input:
   ```sql
   ❯ select * from (values (1), (3), (2), (10), (8)) order by column1;
   +---------+
   | column1 |
   +---------+
   | 1       |
   | 2       |
   | 3       |
   | 8       |
   | 10      |
   +---------+
   5 rows in set. Query took 0.010 seconds.
   ```
   
   Trying to run with an `offset` results in:
   ```sql
   ❯ select * from (values (1), (3), (2), (10), (8)) order by column1 limit 1 offset 2;
   Internal("Unsupported logical plan: OFFSET")
   ❯ select * from (values (1), (3), (2), (10), (8)) order by column1 limit 1 offset 3;
   Internal("Unsupported logical plan: OFFSET")
   ❯ select * from (values (1), (3), (2), (10), (8)) order by column1 limit 2 offset 3;
   Internal("Unsupported logical plan: OFFSET")
   ❯ 
   ```
   
   The answers should be:
   ```
   -- (3)
   ❯ select * from (values (1), (3), (2), (10), (8)) order by column1 limit 1 offset 2;
   -- (8)
   ❯ select * from (values (1), (3), (2), (10), (8)) order by column1 limit 1 offset 3;
   Internal("Unsupported logical plan: OFFSET")
   -- (8) (10)
   ❯ select * from (values (1), (3), (2), (10), (8)) order by column1 limit 2 offset 3;
   Internal("Unsupported logical plan: OFFSET")
   ```
   
   Does that help?
