Hi Bryce, Unfortunately Riak 2.0 final is not yet available but I would be curious to know if the upcoming Bucket Types [1] [2] feature would help you model your problem. You could create a Bucket Type for your allow_mult=true projects and another for lww=true. so you would have something like (extending the notation you used in your email):
* bucket_types/allowsibs/buckets/project-year-month-day/keys/key * bucket_types/nosibs/buckets/project-year-month-day/keys/key where "allowsibs" and "nosibs" are the two bucket types, respectively.
