-----------------------------------------
I find this change is looking good except 1 usability concern I have related to
usability. I left comment in the PR.
> Add fail-fast mode to bounded iteration of StandaloneWalRecordsIterator
> -----------------------------------------------------------------------
>
> Key: IGNITE-10045
> URL: https://issues.apache.org/jira/browse/IGNITE-10045
> Project: Ignite
> Issue Type: Improvement
> Reporter: Ivan Rakov
> Assignee: Alexey Stelmak
> Priority: Major
> Fix For: 2.8
>
>
> Since IGNITE-9294 StandaloneWalRecordsIterator supports bounded iteration.
> That means we can specify "from" and "to" WAL pointers and iterator will
> return records only between given bounds.
> The problem is that in current implementation StandaloneWalRecordsIterator
> just skips segments if they are missing. For example: if we'll specify
> fromIdx=0, toIdx = 10 and segments with indexes=[9, 10] will be missing,
> we'll just silently finish iteration on idx=8.
> To prevent that, we should be able to switch on fail-fast mode, in which
> StandaloneWalRecordsIterator will throw error unless iteration is really
> started from left bound and ended on right bound.
