---------------------------------
Summary: Add support for one-way sync across notebook storages
Key: ZEPPELIN-1294
URL: https://issues.apache.org/jira/browse/ZEPPELIN-1294
Project: Zeppelin
Issue Type: Improvement
Reporter: Hao Xia
Assignee: Hao Xia
Currently, if there are two notebook storages configured, the sync process
treats them equally and can pull changes from either storage. This can cause
confusions if there is a clear distinction between primary and secondary
storages, and the primary storage is managed outside of Zeppelin itself, such
as a local folder that's git controlled. If a notebook is deleted or reverted
to an older version in the primary storage behind Zeppelin's back, the sync
process will overwrite the change with data from the secondary storage, likely
against the user's intention.
The proposal is to enable the scenario with a one-way sync flag, where the
primary storage is treated as the only source of truth and the secondary
storage is merely a mirror of the primary.
