Details

Every time we store a job we do a full scan on the job_eta table to retrieve its eta. The table has a significant size, so we end up scanning more than 1.7M rows. We should add an index to the signature column to avoid that.
Given the size of some of the current tables (eg 2.8 million rows for the mozilla-inbound one), I think trying to add an index now is going to need a failover. I'm hoping bug 1181572 will take a little bit of pressure off, after which I think we're best waiting for the new implementation in bug 1196764.
