[Jackrabbit Wiki] Update of "frm/SegmentStoreModularization" by frm

[Apache Wiki <wi...@apache.org>]

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Jackrabbit Wiki" for change notification.

The "frm/SegmentStoreModularization" page has been changed by frm:
https://wiki.apache.org/jackrabbit/frm/SegmentStoreModularization

New page:
= Segment Store Modularization =

This page describes the process of storing the Segment Store and its related implementation classes in its own bundle, separated from oak-core. The initial target of the analysis are the packages matching the filter org.apache.jackrabbit.oak.plugins.segment.*.

== Backwards dependencies ==

These are the components that depend on the classes contained in org.apache.jackrabbit.oak.plugins.segment.*. This shows how much code in oak-core is coupled with the internal API or with the implementation classes of the Segment Store.

 * org.apache.jackrabbit.oak.plugins.backup.FileStoreBackup;
 * org.apache.jackrabbit.oak.plugins.backup.FileStoreRestore;
 * org.apache.jackrabbit.oak.plugins.value.ValueImpl;
 * org.apache.jackrabbit.oak.util.AbstractCheckpointMBean.

== Forward dependencies ==
