> In the oak-segment-azure, reading the whole journal may be a time consuming
> task, as the blob appends are a bit slow to read. The OAK-8604 introduces an
> improvement, by keeping the most recent journal entry saved as a metadata in
> the journal.log blob. We should allow to use this optimization in
> SegmentStoreMigrator, by adding a new migration parameter -
> {{onlyLastJournalEntry}}. This way, only the last entry in the journal will
> be migrated and it won't require to read the whole journal.
