-----------------------------------------
The patch looks good to me
> It is possible for speed-based throttling to allow Checkpoint Buffer overflow
> -----------------------------------------------------------------------------

> Key: IGNITE-16581
> URL: https://issues.apache.org/jira/browse/IGNITE-16581
> Project: Ignite
> Issue Type: Bug
> Components: persistence
> Affects Versions: 2.11, 2.12, 2.11.1
> Reporter: Roman Puchkovskiy
> Assignee: Roman Puchkovskiy
> Priority: Major
> Fix For: 2.13

> When speed-based throttling is turned on, in the very beginning of a
> checkpoint, there is a short period of time when checkpoint progress
> information is not yet available. Current implementation does not protect the
> Checkpoint Buffer during that period. If there is really high load of writes
> hitting the CP Buffer, it can be overflowed.
