             Summary: TO: Fix Postgres non-performant queries
                 Key: TC-79

    Affects Versions: 2.0.0

The following query takes ~20ms in mysql but ~700+ms in postgres:

https://github.com/apache/incubator-trafficcontrol/blob/master/traffic_ops/app/lib/Schema/Result/DeliveryServiceInfoForDomainList.pm#L41

Also, the following query is not performant when multiple items are passed into the "IN" clause:

https://github.com/apache/incubator-trafficcontrol/blob/master/traffic_ops/app/lib/Schema/Result/DeliveryServiceInfoForServerList.pm#L41

these queries affect routes that traffic ops ORT uses and they need to be performant.
