["Robert Munteanu (JIRA)" <ji...@apache.org>]

Robert Munteanu commented on OAK-3401:
--------------------------------------

[~chetanm] - should we split out the issues from this epic and resolve it as WONTFIX given that OAK-4871 is now in trunk?

If you agree please break the epic links, I don't have karma to do that.

> The scenario for this multiplexing is the following:
> * multiple Oak instances configured using a DocumentNodeStore
> * all DocumentNodeStore instances connect to the same physical backend,
> e.g. a mongod/mongos instance
> * each Oak instance needs a private area that is not shared with the
> other instances ( e.g. /tmp )
> The concept is similar to Unix filesystem mounts managed in /etc/fstab. A 'root' store manages the whole repository, while at certain points other sub-stores take over.
> An example configuration can be:
> {noformat}
> /         <- root store
>  /apps    <- sub-store 1
>  /libs    <- sub-store 1
>  /tmp     <- sub-store 2
> {noformat}
> For more details refer to the thread by [~rombert] at [1]
> Supporting this would require changes both in Document NodeStore layer and in Oak layer
