pub struct RestoreLayer {
pub objects: bool,
pub history_floors: bool,
}Expand description
Per-pipeline registration toggles for
restore_indexes.
The live-cohort pipelines (object_by_owner, object_by_type,
balance) are always restored — they cannot be reconstructed
from anywhere else. The rest is conditional:
- The history floor rows (
object_version_by_checkpoint,package_versions) matter only when some prefix of the chain is unavailable for backfill. A caller whose history cohort replays from genesis skips them — the backfill rebuilds both CFs in full, so restoring them would waste bulk-load work and stamp watermarks the backfill would have to be rewound past. - The raw
objectsCF is needed by the standalone deployment so version-keyed reads are served by the restored snapshot; the embedded-fullnode deployment already has every object version in the validator’s perpetual store and skips the duplicate write.
Fields§
§objects: boolIf true, register the objects pipeline with the restore
driver so each live object lands as an
(ObjectID, version) → StoredObject row.
history_floors: boolIf true, register the object_version_by_checkpoint and
package_versions pipelines so their floor rows at the
restore target are bulk-loaded (see
HISTORY_COHORT’s docs for how the
history seed then rewinds their watermarks).
Implementations§
Source§impl RestoreLayer
impl RestoreLayer
Sourcepub fn all() -> Self
pub fn all() -> Self
Restore every pipeline, including the raw objects CF.
The standalone-binary default.
Sourcepub fn indexes_only() -> Self
pub fn indexes_only() -> Self
Restore only the derived-index pipelines. The embedded-
fullnode default when the perpetual store has pruned
(L > 0) — the fullnode’s perpetual store already holds
every object version, so the objects CF is left untouched
here.
Sourcepub fn live_only() -> Self
pub fn live_only() -> Self
Restore only the live-cohort index pipelines. The embedded-
fullnode choice when nothing has been pruned (L == 0): the
history cohort backfills from genesis and rebuilds
object_version_by_checkpoint and package_versions in
full, so their floor rows (and the restore watermarks that
come with them) must not be written.
