What do you mean by "durability"? Its highly likely that elastic has the same storage guarantees that cassandra does. That said, some people like to have the flexibility of having the golden source elsewhere and the ability to blow away the index & re-index at a whim. There are a number of elastic users, however, where this is not viable - where reindexing their volume of data would take a week or 2.
