Regarding HBase/Redis I've been extracting what I think of as our
process for adding new technology to the stack.  I don't want to
create the perception of checklist that if folks jump through the
hoops somehow there is magically a new tech in the stack, but it also
shouldn't be totally undocumented.

This is a draft.  Y'all are the first folks to see this, so feel free
to poke holes.

1. What problem are we trying to solve?  (Technology should never be
introduced as an end to itself)

2. How could we solve the problem with our current tech stack?  (If
the answer is we can't, then we probably haven't thought about the
problem deeply enough)

3. Are we clear on what new costs we're taking on with the new
technology? (monitoring, training, cognitive load, etc)

4. What about our current stack makings solving this problem in a
cost-effective manner (in terms of $$ and people) difficult?

5. If this new tech is a replacement for something we currently do,
are we committed to moving everything to this new technology in the
future? Or are we proliferating new technologies for specific tasks?

6. Who do we know and trust who uses this tech?  Have we talked to
them about it?  What did they say about it?

7. What's a low risk way to get started?

8. At each step get together a mixed discipline group of senior
enginners (but not just snr-engs) and thrash out the point.
