[jira] [Updated] (IGNITE-17613) Create incremental snapshot

     [ https://issues.apache.org/jira/browse/IGNITE-17613?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Maksim Timonin updated IGNITE-17613:
------------------------------------
    Description: 
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.
