Reference documentation and code samples for the Memorystore V1BETA API module Google::Cloud::Memorystore::V1beta::PersistenceConfig::AOFConfig::AppendFsync.
Possible fsync modes.
Constants
APPEND_FSYNC_UNSPECIFIED
value: 0 Not set. Default: EVERY_SEC
NEVER
value: 1 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
value: 2 Fsync every second. You may lose 1 second of data if there is a
disaster.
ALWAYS
value: 3 Fsync every time new write commands are appended to the AOF. The best
data loss protection at the cost of performance.
