My understanding of what Elias wanted was a counter that simply stored the minimum and maximum values it has ever reached, an optional reset would probably be nice as well. It would be quite helpful when dealing with statistics counters that can decrement.
Then again, I could be wrong. ----- Original Message ----- From: "Russell Brown" <russell.br...@me.com> To: "Elias Levy" <fearsome.lucid...@gmail.com> Cc: "riak-users" <riak-users@lists.basho.com> Sent: Sunday, 9 February, 2014 9:53:42 AM Subject: Re: Max/Min Integer CRDTs? Hi Elias, This is a great time for you to ask, if you’re asking what I think you’re asking.

Do you mean some kind of bounded counter that cannot be incremented beyond (say 1000), or decremented below a certain bound (i.e. non-negative counter?) If so, then the plan is yes, but I’m not sure it is simple. If you have a design for such a thing please share it. We’re working with a team from Universidade Nova de Lisboa as part of the SyncFree project on this, but I’d love to hear your ideas for an implementation. If you want to keep it private feel free to email me off list.
