> Create incremental snapshot
> ---------------------------
>
> Key: IGNITE-17613
> URL: https://issues.apache.org/jira/browse/IGNITE-17613
> Project: Ignite
> Issue Type: Sub-task
> Reporter: Maksim Timonin
> Assignee: Maksim Timonin
> Priority: Major
> Labels: IEP-89, ise
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Incremental snapshot is a lightweight alternative to full snapshot. It bases
> on the non-blocking Consistent Cut algorithm and provides a collection of WAL
> segments that hold logical changes since previous snapshot (full or
> incremental).
> Incremental snapshot should contain:
> * compacted WAL segments
> * meta file with Consistent Cut to restore on
> * binary_meta if it has changed since previous snapshot.
> Incremental snapshot is stored within full snapshot directory.
> Incremental snapshot before creation checks:
> * Base snapshot (at least its metafile) exists. Exists metafile for all
> incremental snapshots.
> * Validate that no misses in WAL segments since previous snapshot.
> * Check that new _ConsistentCutVersion_ is greater than version of previous
> snapshots.
> * Check that baseline topology and cacheGroups are the same (relatively to
> base snapshot).
> More info in IEP:
> [https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=211884314]
> ----
> Highlevel process of creation of incremental snapshot(without consistent cut
> algorithm):
> * Incremental snapshot started with create snapshot command with
> --incremental flag.
> * Incremental snapshot consists of:
> ** WAL segments from previous increment snapshot (or full snapshot in case
> first incremental snapshot).
> ** Changed binary meta and marshaller files.
> ** Snapshot metafile
> * Incremental snapshot are placed to
> {{work/snapshots/mybackup/increments/node01/0001}} folder where
> ** mybackup - name of the full snapshot.
> ** node01 - consistent id of the node.
> ** 0001, 0002, etc - number of incremental snapshot.
> * Incremental snapshot creation consists of the following actions executed on
> each node. The whole process orchestrated by the {{DistributedProcess}} in
> the same manner as the full snapshot creation:
> ** creation of the snapshot folder
> ** awaits while required WAL segments will be archived
> ** copy (hard-linked) required WAL segments to the incremental snapshot
> folder.
> ** creates snapshot metafile.
> * Failover guarantees (remove partially created snapshot, etc) should be the
> same as for the full snapshot.
> * Removal of the full snapshot must also removes all the incremental snapshot
> based on the full one.
> * Removal of the incremental snapshot may be done only for the last one. If
> there are next incremental snapshot (0003, for example) then removal of any
> previous (0001 or 0002) must be restricted.
