> Investigate sorting of snapshot delta pages
> -------------------------------------------
>
> Key: IGNITE-17723
> URL: https://issues.apache.org/jira/browse/IGNITE-17723
> Project: Ignite
> Issue Type: Improvement
> Reporter: Nikita Amelchev
> Assignee: Nikita Amelchev
> Priority: Major
> Labels: ise
> Fix For: 2.15
>
> Time Spent: 10m
> Remaining Estimate: 0h

> The snapshot manager applies delta pages to a partition in a random write
> manner. This leads to a high disk utilisation in a case of some hardware
> disks types.
> Possible solutions:
> - Limit delta applying speed separate with partitions limit.
> - Pre-sort pages.
