I second what Elijah said: "working code".
So far I see just a (very pretty) website, but stricly no code. Not good.
I work in a industry where we
a) do use billions of time series points and
b) are latency and performance sensitive
We like flat (binary) files as well as mmap a lot, and do a lot of C++ for
performance where we'd never ever dream about embedding R. But we do course
use R for analysis and then embed quite some C++ into to "do stuff". We use
Redis (out of process) for a few things, but obviously not "raw data". I like
what I see from influxdb.com, but we are now off-topic for this list.
So colour me "interested" -- but please show some code, or people will tune
out pretty quickly.
