Summary: 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
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.
