Monotonic read consistency means if a process has seen a particular value for the object, any subsequent accesses will never return any previous values. (quoted from http://www.allthingsdistributed.com/2007/12/eventually_consistent.html). Yes, the cache is local to each actor. The actor can

Thanks Reid, we have that implementation for Read Your Writes already. We'd like to implement Monotonic Read Consistency as well. For Monotonic Read Consistency, we were hoping to do Vector Clock comparison but we don't know how to convert the byte[] into different client's time

ity, but gaurantee read-your-writes consistency. Note that read-your-writes is slightly different than just monotonic read consistency, but I'm guessing it's closer to what you had in mind. [1] https://github.com/basho/riak_kv/issues/388 Reid On Dec 5, 2012, at 11:13 PM, "

Monotonic Read Consistency

2012-12-05 Thread Vergara, Jeaneth Aguilar
Hi there, We're trying to implement monotonic read consistency at the client side using Riak's Java client. We're kind of stumped on how to do vector clock comparison so we can ensure that we're always getting the latest version. Any tips would be apprec
