If this is just for doing tests to make sure you get back the data you
expect, I would recommend looking some sort of eventually construct in your
testing. We use Specs2 as our testing framework, and our write-then-read
tests look something like this:
someDAO.write(someObject)
eventually {
someDAO.read(someObject.id) mustEqual someObject
}
This will retry the read repeatedly over a short duration.
Just in case you are trying to do write-then-read outside of tests, you
should be aware that it's a Bad Idea™, but your email reads like you
already know that =)
