Konstantin Boudnik commented on HBASE-11165:
--------------------------------------------
Honestly speaking the latest fashion (not to say obsession ;) with TLA+ doesn't
help anything. It isn't a formal proof of the code correctness nor help to
reconciles architecture contracts, as Alex has pointed out. So while someone
can produce a fancy TLA+ diagram I am not sure I am not sure how many others
will even pay the attention to it. It's like a UML - a good way to share the
responsibility for a bad decision ;)
We have posted the spec in that HDFS JIRA because it was easier to do that
instead of keep the endless argument about nothingness. Will the same be
required here, I wonder?

> This discussion issue comes out of "Co-locate Meta And Master HBASE-10569"
> and comments on the doc posted there.
> A user -- our Francis Liu -- needs to be able to scale a cluster to do 1M
> regions maybe even 50M later. This issue is about discussing how we will do
> that (or if not 50M on a cluster, how otherwise we can attain same end).
> More detail to follow.
