From 05a8f401c20e2a0b35360544aba12905239cc369 Mon Sep 17 00:00:00 2001 From: Yorick Peterse Date: Tue, 19 Sep 2017 00:37:38 +0200 Subject: Reorganize indexes for the "deployments" table This removes the need for a default scope that adds a "WHERE project_id = X" clause. This commit also includes an additional index for Environment#last_deployment, ensuring this query uses just an index scan instead of also applying a Filter.
