GitHub user Ozoubia created a discussion: Recommended IRIS connector for 
Superset 6.x? (TOP / row limit issues with sqlalchemy-iris)

Hi everyone,

I'm running Superset with InterSystems IRIS as a data source and I'm planning 
to move to Superset 6.x.
My current setup uses:

- `apache/superset:4.0.2` (official image)
- `sqlalchemy-iris==0.18.1` 
([caretdev/sqlalchemy-iris](https://github.com/caretdev/sqlalchemy-iris))
- `intersystems-irispython==5.4.0`

While testing Superset 6.x with the same connector, I ran into problems with 
queries involving
row limits. IRIS uses `SELECT TOP n` rather than `LIMIT`, and some generated 
queries didn't work.

A few questions:

1. Is there a newer or recommended connector/dialect for IRIS that works well 
with Superset 6.x?
2. Has anyone successfully used IRIS with Superset 6.x, and if so, with which 
package versions?
3. Are there alternative approaches (e.g. a different driver, JDBC/ODBC bridge, 
or engine spec settings)
   that others use for IRIS?

Any pointers would be appreciated. Thanks!
