Some database implementations are able to run a query in the background and only stall the application when the ResultSet is iterated and the next object has not yet been returned. If the caller is signed in and running a change query the JSON formatter will need to use the starred change collection. Begin loading the starred change collection for the caller before the change query is parsed and executed, giving the database time to load the starred changes in the background. This should reduce some search result latency for signed in users on gerrit-review, where the database is slow but ResultSet loads objects async to the application.
