IGNITE-7584: WAL log throttle implementation
----
> Smooth decrease WAL write speed if low work segments left
> ---------------------------------------------------------
>
> Key: IGNITE-7584
> URL: https://issues.apache.org/jira/browse/IGNITE-7584
> Project: Ignite
> Issue Type: Improvement
> Components: persistence
> Reporter: Dmitriy Pavlov
> Assignee: Dmitriy Pavlov
> Priority: Major
>
> Smooth decrease of the write speed in WAL when approaching the exhaustion of
> current segments in the working directory.
> Now archiver segment switch involves file copying and may be bottleneck of
> speed of grid operation.
> Now if out of work segments occurs, grid put speed drop down to 0 ops/sec
> ocurred.
> This isssue was fixed under IGNITE-7017 with providing new 'NoArchvier' mode,
> but in case archiver based WAL is already used by end-user, it is required to
> have opportunity to smooth decrease speed instead of drop to 0.
