> Add ability to read WAL outside of an Ignite node
> -------------------------------------------------
>
> Key: IGNITE-5558
> URL: https://issues.apache.org/jira/browse/IGNITE-5558
> Project: Ignite
> Issue Type: Improvement
> Components: persistence
> Affects Versions: 2.1
> Reporter: Alexey Goncharuk
> Assignee: Dmitriy Pavlov
> Fix For: 2.1
>
>
> Currently, the WAL iterator can be obtained from the WAL manager when an
> Ignite node is up and running.
> However, it may be extremely useful to read WAL in an 'offline' mode, when a
> node is not started up. This may be required for crash analysis or to export
> committed data to some external systems.
> In the future we can make this even a public interface, however as a starting
> point, I would like to keep it in private package because moving to the
> public package will require Iterator and records to be public too.
> So, as a starting point, we need:
> * An object that will allow us to get WALIterator instances (probably,
> should be closeable)
> * A method on this object which will create an iterator by a file name or
> file names
> Using this object should not require an active Ignite instance running.
