----------------------------------
Summary: Allow to only copy last journal entry in the
SegmentStoreMigrator
Key: OAK-8640
URL: https://issues.apache.org/jira/browse/OAK-8640
Project: Jackrabbit Oak
Issue Type: Story
Components: segment-azure
Reporter: Tomek Rękawek
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.
