Enum FsyncPolicy 

pub enum FsyncPolicy {
    Strict,
    Batched,
    Relaxed,
}

When GraphDb calls Fs::sync after a WAL append.

Default is Strict: every log_then_apply_with fsyncs (single insert_node / set_prop). Ingest and write_batch emit one WalRecord::Batch and fsync once at that frame (Batched). Relaxed skips WAL sync; GraphDb::snapshot is still durable via write_atomic. Crash-recovery DST stays Strict.

Variants

Strict

Every WAL commit calls fs.sync (today’s behavior).

Batched

Sync only at a Batch frame end. Single-op path stays Strict unless this policy is set on the database.

Relaxed

Never call fs.sync. GraphDb::snapshot still syncs via write_atomic.
