Default: EVERYSEC\n\nGenerated from protobuf enum `APPEND_FSYNC_UNSPECIFIED = 0;`\n\n### NO\n\n Value: 1\n\nNever fsync. Normally Linux will flush data every 30 seconds with this\nconfiguration, but it's up to the kernel's exact tuning.\n\nGenerated from protobuf enum `NO = 1;`\n\n### EVERYSEC\n\n Value: 2\n\nfsync every second. Fast enough, and you may lose 1 second of data if\nthere is a disaster\n\nGenerated from protobuf enum `EVERYSEC = 2;`\n\n### ALWAYS\n\n Value: 3\n\nfsync every time new write commands are appended to the AOF. It has the\nbest data loss protection at the cost of performance\n\nGenerated from protobuf enum `ALWAYS = 3;`"]]
