------------------------------------
Summary: Add 'restore' method to NodeStore apis
Key: OAK-1357
URL: https://issues.apache.org/jira/browse/OAK-1357
Project: Jackrabbit Oak
Issue Type: Improvement
Components: core
Reporter: Alex Parvulescu
Assignee: Alex Parvulescu
OAK-762 introduced a checkpoint mechanism which allows for the creation of a
snapshot of the current state, referenced by a string.
Other than internally for the async indexing I'd like to leverage this in the
case of an external (non blocking!) backup process (for both mongomk and
rdbstore) and probably for the tarmk simple failover scenario.
What is currently missing is an option to restore the current state to a
captured snapshot, which is the point of this issue.
I'm proposing we add a _ #restore(String checkpoint)_ method to the NodeStore
apis which resets the current head to the provided state.
This could probably throw an exception in the case the provided checkpoint
doesn't exist, and it would also fail ongoing transactions as they don't apply
anymore.
