Francis Christopher Liu commented on HBASE-25761:
-------------------------------------------------
Been working on this the past couple of weeks. I'm hacking my existing Root
Table branch and converting it to first hbase:meta region as root. I've been
making changes to get the bare minimum working for us to better understand the
pros/cons.
> POC: hbase:meta,,1 as ROOT
> --------------------------

> Key: HBASE-25761
> URL: https://issues.apache.org/jira/browse/HBASE-25761
> Project: HBase
> Issue Type: Sub-task
> Reporter: Michael Stack
> Assignee: Francis Christopher Liu
> Priority: Major
>
> One of the proposals up in the split-meta design doc suggests a
> sleight-of-hand where the current hard-coded hbase:meta,,1 Region is
> leveraged to serve as first Region of a split hbase:meta but also does
> double-duty as 'ROOT'. This suggestion was put aside as a complicating
> recursion in chat but then Francis noticed on a re-read of the BigTable
> paper, that this is how they describe they do 'ROOT': "The root tablet is
> just the first tablet in the METADATA table, but is treated specially -- it
> is never split..."
> This issue is for playing around with this notion to see what the problems
> are so can do a better description of this approach here, in the design:
