Overview

Available fsync modes.

Constant Summary

APPEND_FSYNC_UNSPECIFIED =

Not set. Default: EVERYSEC

0

NO =

Never fsync. Normally Linux will flush data every 30 seconds with this configuration, but it's up to the kernel's exact tuning.

1

EVERYSEC =

fsync every second. Fast enough, and you may lose 1 second of data if there is a disaster

2

ALWAYS =

fsync every time new write commands are appended to the AOF. It has the best data loss protection at the cost of performance
