I am using riack (https://github.com/trifork/riack <https://github.com/trifork/riack>) as a client. I started using it before riak-c-client had been released. The sequence of events for the client is:
1. Perform get/set: only the get succeeds 2. Perform get/set again: neither get nor set succeeds 3. Perform get/set third time: riack crashes, i.e. a crash occurs somewhere before the get functions returns Sargun, I meant that the client process crash, not the riak framework. The riak processes remain operational while its clients keep crashing. - Hristo > On Sep 23, 2015, at 6:28 PM, Sargun Dhillon <sdhil...@basho.com> wrote: > > if there is a failure, and leader is re-elected, the epoch of the ensemble > changes, so you may have to refetch the object to get a new causal context in > order to perform another write.
