Redshift Order BY LIMIT being ignored from query

Question

Hi all,
I faced an strange scenario in a simple query on Redshift and i'm trying to understand if this is a bug or normal (i dont think so) behavior:

My query (for example only):

SELECT * 
FROM table 
WHERE id = 'UUID' 
ORDER BY date DESC 
LIMIT 1

This query, for some unknown reason are returning all records matching with WHERE clause but discarding order by and limit clauses.
Even on "explain" from query editor it is not being considered.

However if change the query to something like this:

SELECT * 
FROM table 
WHERE id LIKE 'UUID' 
ORDER BY date DESC 
LIMIT 1

Basically changing the operator "=" per "LIKE" in WHERE clause my query works fine,  the response returns only a specified limited records ordered correctly.
Some hints: this strange behavior only happened in my tests when the parameter in WHERE clause is a string DistKey with UUID content

Answer

I could not replicate this behavior on my table. Could it be something very specific to your table and your data? Maybe best to open a support ticket and see what they find.
