I think the important thing is the proposal should be interersting to you. Thus I do not want to "assign" things. I would say the best idea is to look into more data structures: http://ieeexplore.ieee.org/document/7328521/ Or possibly developing some form of lock management: http://www.exploredatabase.com/2014/04/distributed-lock-manager-concurrency.html Or building higher level datastructures ontop of CRDTs https://ignite.apache.org/features/datastructures.html To do these we need to solve/handle a couple of issues. Building something that does a leader election makes sense as well. the open question in my mind is will we implement something like this: https://issues.apache.org/jira/browse/VXQUERY-180?jql=labels%20%3D%20gsoc2017 Where machine do direct communication vs lazy gossip replication. Also I have been thinking hard about the per-node vs shared hash maps. I thing what we need to there is unify those concepts and make the key of the hashmap be useful for expressing more arbitrary concepts like "only replicate this to nodes name xyz" or "only replicate this to nodes in datacenter b" or "dont replicate this at all it is only local data" Having a distributed structure that I can lock is most interesting to me. Even if the lock takes 30 seconds to acquire by reaching a quorum of nodes, wondering if we can implement something like this: https://www.google.com/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=bakery+algorithm&* Anyway there is a lot of ideas there maybe you can take one in a more specific direction.
