Durability enum

How commits reach stable storage.

Why an enum and not a flag: the three levels are distinct guarantees an app chooses on purpose, and each maps to one engine setting.

Inheritance
Available extensions

Values

full → const Durability

Every commit is flushed before it completes (default): a committed transaction survives a power loss.

const Durability('full')
noMetaSync → const Durability

Data is flushed on commit but the metadata page is not: a system crash may undo the last transaction, never corrupt the database.

const Durability('no_meta_sync')
noSync → const Durability

Flushing is left to the operating system: a system crash may undo the last transactions. An app crash loses nothing.

const Durability('no_sync')
