Struct StorageStatistics

}

Durable byte accounting by key family, for growth diagnosis and operator metrics. All values are exact sums of stored key+value lengths for the family, taken from one read view; they exclude redb’s copy-on-write slack (compare against Store::storage_file_bytes).

Fields

data_keys: u64

Canonical data rows (records, occurrences, postings, catalogs, …).

data_bytes: u64

Total key+value bytes of canonical data rows.

history_keys: u64

Retained MVCC history rows.

history_bytes: u64

Total key+encoded-history bytes.

log_keys: u64

Retained command-log rows (__log__/<lsn>).

log_bytes: u64

Total command-log bytes.

receipt_keys: u64

Retry-receipt rows (receipts plus their expiry index).

receipt_bytes: u64

Total retry-receipt bytes.

admission_waits: u64

Number of bounded admission-lock waits (including timed-out waits).

admission_wait_ms: u64

Milliseconds spent waiting for admission-lock ownership.

checkpoints: u64

Number of explicit durability checkpoints.

checkpoint_wait_ms: u64

Milliseconds spent in explicit durability checkpoints.
