> Project: Ignite
> Issue Type: Improvement
> Components: persistence

>
> Time Spent: 20m
> Remaining Estimate: 0h

> At the moment we have the option to delete segments from the middle of the
> archive via the *FileWriteAheadLogManager#truncate*. This creates gaps in the
> archive and makes it invalid.
> It should be possible to delete segments sequentially up to the upper
> boundary. It has also been found that there is no protection against segment
> deletion, which may be needed for a binary recovery.
> Also need to get rid of the physical check when reserving segments through
> the *FileWriteAheadLogManager#reserve*.
