----------------------------------------
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.
