I have a query in Retool, it is a simple "List all contacts" query
SELECT
*
FROM
contacts
ORDER BY
contacts.first_name ASC;
When I disable retool cache this query takes about 1.2s on average. But with cache enabled it can take anywhere from 2s - 17s. This seems to be happening on multiple queries, enabling cache typically doubled run time.
FWIW I notice this most on Monday mornings and it seems to level out over the week, but that is purely anecdotal.
