A lot of disadvantages connected with using of Cassandra DB have been mentioned in this thread. What about the advantages? Does the multi LIM system stil loose the ability of make changes in the configuration if one of the LIM is out of order? I don`t have an opportynity to check it, but from my point of view, this is quite logical that in case of having several independent writeable DB means that changes should be applied to the configuration even if one of the LIM is out of order. Is it possible to make data_backup? What happens when LIM comes back and data reload is executed, do we loose changes?
