Has no need? Did you just make this up? We used MemSQL for real-time data for 2 years. All data is fully persistent, but the rowstore tables are also fully held in memory compared to columnstores which are mainly on disk. There's nothing fragile about it. SQL Server's Hekaton, SAP's HANA, Oracle's Times Ten, and several other databases do the same. Timesliced totals is just a SQL query, and mediation or some other buffer from live numbers for customers is up to every business to decide, not some default proclamation for an entire industry. |
