Mikhail Antonov commented on HBASE-11165:
-----------------------------------------
[~apurtell]
auto-tunable memstores sound interesting to me. As of the options to implement
that, we probably can tune them so the frequency of flushes is kept the same
(so say, when we see less flushes for a particular memstore last 3 minutes that
the avg. last 24 hours, we make this memstore smaller, when we see more
frequent flushes, we make it bigger?
What do you think, how expensive is to resize memstore and how often we may
need it? Another thing - how it might affect 99th latency.

Fast assignment assuming that everything is local binds us to non-splittable
META, right?
> Scaling so cluster can host 1M regions and beyond (50M regions?)

> 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.
