[jira] [Created] (IGNITE-7017) Reconsider WAL archive strategy

Alexey Goncharuk created IGNITE-7017:
----------------------------------------

             Summary: Reconsider WAL archive strategy
                 Key: IGNITE-7017
                 URL: https://issues.apache.org/jira/browse/IGNITE-7017
             Project: Ignite
          Issue Type: Task
    Affects Versions: 2.3
            Reporter: Alexey Goncharuk
             Fix For: 2.4


Currently, we write WAL files in work directory and then copy them to the archive after the segment is closed. 
This was done to overcome XFS bug which leads to a double fsync cost immediately after file creation. This approach leads to excessive disk usage and can be optimized, especially for LOG_ONLY mode.
