> There are a couple problems that can affect our ability to troubleshoot state
> restore from changelog.
> 1. KeyValueStorageEngine logs a message for every 1M messages restored, but
> it doesn't print anything for smaller stores. We should add a message to
> report the final number of entries restored.
> 2. While the "restore-time" metric is a gauge, the
> KeyValueStorageEngineMetrics "messages-restored" and "messages-bytes" are
> both counters, and counters are often reported in terms of deltas so the
> value disappears after one data point. Since these values only matter for the
> beginning of the job, we should switch them to gauges so the value is
> retained for later monitoring.
