It's been a while since I've been an insider, and these comments are purely from an outside perspective, interacting with such users. Vertica is seeing use for more historical stuff, and where the time series queries are pretty simple. Informix time series is doing ok, and has better support for rich queries, but isn't really playing realtime. MemSQL has the realtime perf (hi guys!) but needs to beef up on expressiveness. SAP HANA could do it, but not seeing major uptake there. Still seeing lots of ad hoc solutions, and the expected experimentation with the usual hadoop menagerie (spark is helping make that practical). The sensor stuff gets interesting at scale. Individual sources may not be producing data that quickly, but in aggregate it can be entertaining volume. Esp. when it comes to mobile things, and correlations become interesting to look at. Deep thoughts need to wait for the coffee to kick in. I suspect we'll see a lot of reinvention of technology to cope with these problems; perhaps even open source..
