> We've had a situation where our backup-restore flow did not include summary.db component
for a large file with a lot of keys. This caused Cassandra on the restored node to take a
long time to boot (while it was building the summary).
> The last message was about opening a few sstables. It would be nice to also include a
debug line about building summary, which then operators can use to check if a missing summary
file is expected.
