Matteo Bertozzi commented on HBASE-8642:
----------------------------------------
{quote}is that to seperate data and meta to enable possible file sharing among
tables. This could be a new catalog system for hbase.{quote}
Yeah that's the idea... it not just file sharing between table/snapshots is
also the ability to switch to managing blocks directly and avoid to rewrite
everything during compactions.
{quote}One byte (256 items could be attached) for each node anchor under .data
tree.{quote}
Not sure what you mean with this... The file placement using the first bytes of
the hash/name is just to avoid the problem of too many files in a directory
that old filesystems have, and a different way to store stuff removing the
knowledge of table/region/cf that today is hardcoded. This doesn't really have
effect on all the capabilities that you'll gain from the richer metadata system.
(This stuff is starting being off topic here, since is not related 100% with
this jira, if you've other question/suggestions/... just write it on HBASE-7806)
