A long journey from rebar2 to rebar3 Rebar 3 has recently started to surface out of alpha state and entered beta1, about time for the crazy people like me to abandon tried and tested tools to venture into the great vastness of the unknown!
So with a backpack, hiking shoes, food for about a week and a direct line to the rebar3 IRC channel I set off to migrate sniffle from rebar2 to rebar3.

To garbage collect the OR Set we do the following, we take some of the elements of the remove set, and delete them from both the add and the remove set - this way we save the space for them and generate a new baseline.

So they have one big drawback, most of them collect garbage, and over time that can sum up to a lot making them pretty unpractical in many cases. Collecting this garbage is a bit tricky, since usually it means synchronising the data - which going back to the eventual consistent stuff prevents either A or P.
