Shouldn't "100" be replaced by etcdCompactFrequency? I.e.

if rev%etcdCompactFreqency == 0 && rev > etcdCompactFreqency {

Thanks! I added distinct var, named etcdCompactWindow, for more generalization and flexibility.
etcdCompactWindow is set to 100 as default.

And, I updated codes to apply concept of compact window. Please check the following commits: 73062f1

go func() {
if err := admin.etcdCompact(rev); err != nil {
log.Error("Metadium - failed to compact",
"rev", rev, "took", time.Since(tstart))
}
}()
}
}
