Re: Querying Across Apps on Heroku
I've seen live DB to DB solutions fail many times before. But I'm willing to admit I could have been doing it wrong :) My advice is to go with on DB and partition the app. Others may have better advice. - Ken On Jan 26, 2010, at 2:51 AM, Splashlin wrote: I have multiple apps on Heroku that each have their own database.

Should I use one massive database on the new application and just point all my other apps to it or is there a way to move from database to database collecting the information?

Re: Querying Across Apps on Heroku
I'd consider providing an internal web service in your existing applications that your summary application can query using a REST API.

Re: Querying Across Apps on Heroku
There are many ways to solve this problem. One way: Have each app provide a search service that the central app can call. This works if you don't mind having the data segmented by application. Second way: If the results need to be ranked as a whole then you should put all of the data into a single database.

Re: Querying Across Apps on Heroku
I'd probably go this route as well. ActiveResource in your summary application can make this pretty easy. On Tue, Jan 26, 2010 at 12:11 PM, Matthew A.
