Title: Message Title

Kirill Tkalenko updated an issue   Ignite / IGNITE-17267 Preparing a checkpoint for a DeltaFilePageStore Change By: Kirill Tkalenko To implement the *DeltaFilePageStore*, we need to prepare a checkpoint for their creation. What should be done: # Sort dirty pages (*FullPageId*) by *groupId*, *partitionId*, *pageIdx*; # In several threads, write dirty pages in batches for each partition and know the number of these pages. What can we look at: * *org.apache.ignite.internal.pagememory.persistence.checkpoint.CheckpointWorkflow#beginCheckpoint* * *org.apache.ignite.internal.pagememory.persistence.checkpoint.CheckpointWorkflow#splitAndSortCheckpointPagesIfNeeded* * *org.apache.ignite.internal.pagememory.persistence.checkpoint.Checkpointer#writePages* Some implementation notes: * We can replace *CheckpointWorkflow#parallelSortThreshold* with a constant at 40k, according to the article from 1.
