Description

We should implement a basic progress indicator for compaction displaying percent completed. This could be done by estimating the number of nodes from the entries in the gc.log and the timestamp of the last entry in the journal.log. Such a feature would explicitly not give an ETA as too many factors have an impact here (concurrent activity, IO bandwidth, quota, etc.).
