+# Note: It is VERY important to ensure that a migration does not lock for a
+#       long period of time and to ensure that each individual migration does
+#       not break compatibility with the *previous* version of the code base.
+#       This is because the migrations will be ran automatically as part of the
+#       deployment process, but while the previous version of the code is still
+#       up and running. Thus backwards incompatible changes must be broken up
+#       over multiple migrations inside of multiple pull requests in order to
+#       phase them in over multiple deploys.
+#
+#       By default, migrations cannot wait more than 4s on acquiring a lock
+#       and each individual statement cannot take more than 5s. This helps
+#       prevent situations where a slow migration takes the entire site down.
+#
+#       If you need to increase this timeout for a migration, you can do so
+#       by adding:
+#
+#           op.execute("SET statement_timeout = 5000")
+#           op.execute("SET lock_timeout = 4000")
+#
+#       To whatever values are reasonable for this migration as part of your
+#       migration.
