> Make partition generation increase non-blocking

> Key: IGNITE-26339
> URL: https://issues.apache.org/jira/browse/IGNITE-26339
> Project: Ignite
> Issue Type: Improvement
> Reporter: Kirill Tkalenko
> Assignee: Kirill Tkalenko
> Priority: Major
> Labels: ignite-3
>
> At the moment, increasing the partition generation (on its destruction) is
> done with a small lock, it would be good to make it non-blocking. To increase
> the performance of the checkpoint and the partition destruction operation.
> High-level idea:
> On each operation of writing a dirty page, check that if the partition
> generation has changed, then skip such a page and do nothing.
> This can be achieved, for example, by using an operation counter and some
> flag "partition destroyed". When the operation starts and sees that the flag
> has changed, then skip the operation, if nothing has changed, then the
> destruction of the partition will change the flag and wait for all operations
> to complete and then change the partition generation.
> It can also, within the framework of this task, get rid of cleaning the dirty
> page on the checkpoint record.
