Another way may be voltdb. Since it's partitioned+single-thread/partition, and cross-partition queries are slow, you'll probably have to make a query for each partition and group results on the app.

I specialize in an in-memory analytics (business intelligence) platform called "QlikView" or "Qlik". It operates on top of RDBMSs/operational databases, so it batch processes data on a daily or hourly basis usually.
What is your insert/update/delete rate? If low, maybe look at postgresql in-memory column-store https://github.com/knizhnik/imcs/

Also curious.
