Subject [jira] [Created] (OAK-4243) Oak Segment Next Module

----------------------------------

             Summary: Oak Segment Next Module
                 Key: OAK-4243
                 URL: https://issues.apache.org/jira/browse/OAK-4243
             Project: Jackrabbit Oak
          Issue Type: Epic
          Components: segmentmk
            Reporter: Michael Dürig
            Assignee: Michael Dürig
             Fix For: 1.6


There is a couple of issues requiring us to change the segment format in a non compatible
way (OAK-3348, OAK-2896, OAK-2498, OAK-4201). 

We should introduce a new module here
* to minimise ripple effect on concurrent development work in other parts of Oak and upstream
projects
* to be able to cleanly migrate existing repositories via a side grading
* to cleanly separate breaking changes from the existing code base

The plan is roughly to:
* Create new module (called {{oak-segment-next}} for now, will discuss names later)
* Apply patch prepared for OAK-3348
* Discuss and decide on final name and refactor accordingly 
* Reactor affected tooling such that the targeted segment store can be specified via an option.
Keep default at {{oak-segment}}.
* Once sufficiently stabilised, deprecate {{oak-segment}}. Make this one the default in switch
the default target for tooling.

I will create respective issues as needed.
