-------------------------------------
[~astelmak] The PR has too many merge conflicts after implementation of
IGITE-9909. Could you please pull the latest changes form master branch and
resolve conflicts?
> Copy only actual amount of data during archiving of WAL segment
> ---------------------------------------------------------------

> Key: IGNITE-9903
> URL: https://issues.apache.org/jira/browse/IGNITE-9903
> Project: Ignite
> Issue Type: Improvement
> Reporter: Andrey Gura
> Assignee: Alexey Stelmak
> Priority: Major
> Fix For: 2.8
>
>
> Current WAL archiver implementation copies full WAL segment to the archive
> while actual size of the segment can be significantly less then
> {{maxWalSegmentSize}} (segment files are preallocated for max possible
> segment size).
> In order to reduce disk space consuming we need copy only actual data of
> segment using {{SWITCH_SEGMENT_RECORD}} as marker. It will require some kind
> of WAL iterator implementation that will just copy WAL records using
> information about record size without records deserialization.
