Agree with your analysis. At Netsil, one of the big factors that we considered was average query latency and fast-aggregations over high cardinality, multi-dimensional data. Few of our early customers told us that when they deployed solutions from other vendors (with storage engines such as Cassandra) at scale (800+ monitored instances), they would have to wait for several minutes to let the data render on their dashboards for a 1-day aggregation query. So, it was not just the scalable ingestion that was paramount, fast ad-hoc analytics functionality was equally important to us.
