--------------------------------------
Summary: AbstractFilePageStoreIo#renameFilePath re-reads the header
Key: IGNITE-27575
URL: https://issues.apache.org/jira/browse/IGNITE-27575
Project: Ignite
Issue Type: Improvement
Reporter: Ivan Bessonov
As an optimization of checkpoint we should avoid re-reading delta files, and
re-allocating the buffers to do so. This is an expensive operation in cases
where there are a lot of delta files.
Rename must reuse already existing meta-information.
