Summary:
Slowness and timeout caused by an overload on our reader database

Impact:
Major, Pipefy was inaccessible for less than a minute

Detection:
Engineering team noticed the overload on the database through the monitoring tools

Root Cause:
An index in production started to be inefficient for a specific query, which degraded the performance of the core database

Resolution:
A new index was created increasing the efficiency for that query.
