-------------------------------------
[~tmueller], [~chetanm] FYI.
> FileDataStore with configurable path based structure
> ----------------------------------------------------
>
> Key: OAK-4492
> URL: https://issues.apache.org/jira/browse/OAK-4492
> Project: Jackrabbit Oak
> Issue Type: New Feature
> Components: blob
> Environment: external File Data Store
> Reporter: Dheeraj Khanna
> Labels: features
>
> Configuration for path based structure in the FDS so that we can have more
> granular control over FDS growth and cleanup operations. We can have a
> datastore root under which level 1 can be configurable on basis of number of
> paths needed (index, application1, application2 etc) and rest of the
> management of blobs under each asset can be done in the way they are done
> today.
> Something like:
> datastoreroot
> |
> |___path1 (indexes)
> | |__aa
> | | |__a1
> | | |__a2
> | |
> | |__bb
> | |__b1
> | |__b2
> |
> |___path2 (app1)
> | |__aa
> | | |__a1
> | | |__a2
> | |
> | |__bb
> | |__b1
> | |__b2
> |___path2 (archived blobs)
> | |__aa
> | | |__a1
> | | |__a2
> | |
> | |__bb
> | |__b1
> | |__b2
> |
> For example:
> 1. datastoreroot/path1 (indexes)- folder for index binaries - so that DSGC
> for previous lucene index binaries can be contained in a separate area and
> can be run independent of application blob DSGC.
> 2. datastoreroot/path2 (app1)- in case there are multiple applications on the
> same instance. This could help with backups etc.
> 3. datastoreroot/path3 - folder for archival use case - Eg: In case of
> archival of older blobs the binaries can be moved to this location. Again
> helps with bringing efficiency to the 'current' data set as only current data
> set needs to be backed up on regular basis. Use case also requires to be able
> to restore a archived blob into current data set, if required.
