Fields

tier_budget_bytes: u64

The resolved RAM budget (whole store — Σ per-shard slices).

tier_effective_target: u64

The unified demote target (budget·19/20 − index floor − stub floor, saturating). 0 = the floor alone exceeds the budget.

cold_keys: u64

Currently-cold keys.

cold_bytes: u64

Σ original weights of currently-cold values.

stub_bytes: u64

RAM the cold stubs cost (Σ ENTRY_OVERHEAD + key heap bytes).

index_reserved_bytes: u64

The index/view memory floor fed on the reaper tick.

vlog_size_bytes: u64

Vlog bytes on disk.

vlog_live_bytes: u64

Vlog live (non-dead) bytes.

vlog_files: u64

Vlog file count.

vlog_epoch: u64

Vlog compaction epoch (retired files).

demotions_total: u64

Keys demoted since boot.

promotions_total: u64

Keys promoted back since boot.

peek_preads_total: u64

No-promote peek record reads — one per cold row swept by hydration / backfill / digest / export.

batch_submissions_total: u64

Batched cold-read submissions — one per peeked page.
