Query Database Node takes a long time

This query is simple enought

select noteId , miscMattersMainId , createdOn, createdBy , note from PLSM_note

Those are the only fields in the table and only two records in PLSM_note, 

This is being executed against the pre-defined data source that comes with Appian with almost no load on the server.
For reference, when I run this same query in the loud Database/MyPHPAdmin I get

Showing rows 0 - 2 (3 total, Query took 0.0003 seconds.)

So what's going on as it's taking more than five minutes to complete the execution?
