Description

In https://apacheignite.readme.io/docs/write-ahead-log#section-disabling-wal-archiving there is an error. The documentation says that " instead, it will overwrite the active segments in a cyclical order". In fact, when walWork == walArchive, the whole folder behaves as a sequential log, where new files are sequentially created (0, 1, 2, 3, ...) and old files are eventually truncated. Also, need to clarify the wal size setting in this mode.
Ask dpavlov and akalashnikov for details.
