> We want to keep many copies of snapshots on disk so that we can debug the
> problem afterward. However, the snapshot can be large, so we added a feature
> that allow the server to dump/load snapshot in a compressed format (snappy or
> gzip). This also benefit db loading and snapshotting time as well.
> This is also depends on client workload. In one of our deployment where
> clients don't compress its data, we found that snappy compression work best.
> The snapshot size is reduced from 381M to 65MB. Db loading/and snapshotting
> time is also reduced by 20%.
