Jun Wu 66cef07cf9 indexedlog: add a fsync option to Log and Index ... Summary: Add a way to explicitly `fsync` data to reduce changes of data corruption in case of hard reboots. If `fsync` is set on a `Log`, it sets `fsync` recursively on its indexes and checksum tables. If frequent `fsync` is an issue, it might be possible to only `fsync` the source of truth (log and meta) and have other logic to rebuild indexes on demand. `fsync` on btrfs seems to be relatively cheap (comparing to ext4), so maybe this is fine for btrfs users.
