AppendFsync(value)

Possible fsync modes.

Enums
Name	Description
`APPEND_FSYNC_UNSPECIFIED`	Not set. Default: EVERY_SEC
`NEVER`	Never fsync. Normally Linux will flush data every 30 seconds with this configuration, but it's up to the kernel's exact tuning.
`EVERY_SEC`	Fsync every second. You may lose 1 second of data if there is a disaster.
`ALWAYS`	Fsync every time new write commands are appended to the AOF. The best data loss protection at the cost of performance.
