Enis Soztutar commented on HBASE-11165:
---------------------------------------
One other thing to consider is that we want to put even more data per region
entry in meta. First, we would like to keep a history of RS assignments for the
region in meta (this is for debugging + new assignment design). Second, ideally
we would want to keep the region files in meta as well and get away without
doing reference files, etc. It will ultimately depend on the new master design
of course when these can go in. So I would say the current size calculations
might not be relevant in the longer term.
> 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.
