Another thing that occurs to me is that anyplace I've used a key external to the application would have to be dealt with. For example, one of our apps has an RSS feed that our managers use to keep track of whether customers have uploaded new information. This looks like:
http://myapp.com/rss?cust=DAFHP983RPFDSALFHDSKLFJHLSDKAFH (where the gobledegook is the datastore key) My managers would need to update all their bookmarks, since I believe that key has the name of the app pickled in it someplace, right? Is there any way to avoid having the keys change when I switch to HR? If not, is there a way that I could decorate database queries so that they quietly turn old keys into new ones? -Joshua On Jul 5, 2011, at 3:35 PM, Joshua Smith wrote: > I have several apps and I've got this pesky to-do list item for all of them, > to switch them over to the HR datastore. > > In preparation, I've read blog entries by people who have done this, and I'm > still on the fence about whether it is worth the trouble. > > I get very few datastore timeouts in my apps, and periodic maintenance has > never really been an issue. > > I've read about gotchas with eventual consistency, and it seems unlikely that > I could convince myself that I'm safe from this for any reasonably complex > app. (I'm not concerned that I cannot reprogram the apps to fix the problem, > but rather I'm concerned that I could not ensure there weren't going to be > problems.
