[jira] [Created] (IGNITE-17446) Determine priority between checkpoint and merge delta files

Kirill Tkalenko created IGNITE-17446:
----------------------------------------

             Summary: Determine priority between checkpoint and merge delta files
                 Key: IGNITE-17446
                 URL: https://issues.apache.org/jira/browse/IGNITE-17446
             Project: Ignite
          Issue Type: Improvement
            Reporter: Kirill Tkalenko
             Fix For: 3.0.0-alpha6


When creating delta files in parallel and merging them with the main partition file, the write amplification may increase, and they may begin to interfere with each other. 

In RocksDb, these processes run in parallel, but checkpoint threads have higher thread priority. 

I think it can be done by analogy, but without thread priorities, but with slowing down the threads of the delta file merge.
