[jira] [Updated] (IGNITE-13831) Move WAL archive cleanup from checkpoint to rollover

     [ https://issues.apache.org/jira/browse/IGNITE-13831?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Kirill Tkalenko updated IGNITE-13831:
-------------------------------------
    Description: 
Users expect *DataStorageConfiguration#maxWalArchiveSize* to mean that WAL archive will not exceed this value, but it is not.
It seems that to reduce the chance of getting into a situation when we exceed WAL archive, it will be lowed when we clean it when switching to a new segment than at the end of the checkpoint. It is proposed to move the archive cleanup to *FileWriteAheadLogManager#rollOver* when the *DataStorageConfiguration#maxWalArchiveSize* is reached.

  was:
At the moment, WAL archive is cleared at the end of the checkpoint, which does not seem correct and needs to be moved to the *FileWriteAheadLogManager*. 

It is suggested to clear WAL archive in *FileWriteAheadLogManager#rollOver* when the *DataStorageConfiguration#maxWalArchiveSize* is reached.
