public class ConfigNotesMigration extends NotesMigration
gerrit.config.
This class controls the state of the migration according to options in
gerrit.config. In general, any changes to these options should only
be made by adventurous administrators, who know what they're doing, on
non-production data, for the purposes of testing the NoteDb implementation.
Changing options quite likely requires re-running RebuildNoteDb. For
these reasons, the options remain undocumented.

NotesMigrationUpdates to change data are written to NoteDb refs, but ReviewDb is still the source of truth. Change data will not be written unless the NoteDb refs are already up to date, and the write path will attempt to rebuild the change if not.
If false, the behavior when attempting to write depends on
readChanges(). If readChanges() = false, writes to NoteDb
are simply ignored; if true, any attempts to write will generate an
error.
writeChanges in class NotesMigrationpublic boolean readChanges()
NotesMigrationChange data is read from NoteDb refs, but ReviewDb is still the source of truth. If the loader determines NoteDb is out of date, the change data in NoteDb will be transparently rebuilt. This means that some code paths that look read-only may in fact attempt to write.
If true and writeChanges() = false, changes can still be read from
NoteDb, but any attempts to write will generate an error.

If true, change IDs are read from refs/sequences/changes in
All-Projects. If false, change IDs are read from ReviewDb's native
sequences.
