Redo logs. Feature

Hi Team! Oracle DB have very powerful feature for recovery operations http://docs.oracle.com/cd/B28359_01/server.111/b28310/onlineredo001.htm Is it possible to realize something similar?

Hi Alex,

in BaseX, the current way to avoid loss of data is to create regular backups, e.g. via the integrated CREATE BACKUP command [1]. The concept of the Pending Update List [2] helps a lot to avoid corruptions during single database updates. I agree that a fully automatic recovery framework may be desirable, but is currently out of scope. This may change when we will eventually switch to MVCC [3].
