pub async fn write_version_hint(
object_store: &ObjectStore,
base: &Path,
version: u64,
)Expand description
Write the version hint file after a successful commit.
The hint is stored as JSON: {"version":N}. This write is best-effort —
failures are logged and ignored, since the hint only accelerates reads and
never affects correctness (readers verify the hinted version and probe
upward from there). It is a no-op for detached versions and for stores that
do not benefit from a hint (see uses_version_hint).
