Summary: Improve work with delta files at checkpoint
Key: IGNITE-26311
URL: https://issues.apache.org/jira/browse/IGNITE-26311
Project: Ignite
Issue Type: Improvement
Reporter: Kirill Tkalenko
At the moment, working with delta files when writing dirty pages is quite
confusing.
Creation of delta files occurs immediately before writing a dirty page at a
checkpoint or page replacement, and then we immediately write this page.
Perhaps from this point of view, the description looks correct, but in the code
it is implemented a little more complicated and each time we have to unwind
this logic, which would be better for us to improve it.
Also, if we fix this, we will be able to improve the logic of writing dirty
pages when deleting partitions. Where we can filter out dirty pages that do not
need to be written. Now it is difficult to do and will complicate the code even
more.
