Hi, suppose I have two data centers and want to coordinate a bunch of services in each data center (for example to load data into a per-DC system that is not DC-aware (Solr)).
Does it make sense to use CAS functionality with explicit LOCAL_SERIAL to 'elect' a leader per data center to do the work? So instead of saying 'for this query, LOCAL_SERIAL is enough for me' this would be like saying 'I want XYZ to happen exactly once, per data center'. - All services would try to do XYZ, but only one instance *per datacenter* will actually become the leader and succeed. Makes sense? Jan
