Fields

pending_wal_bytes: usize

Bytes buffered in the WAL but not yet fsynced. Always 0 in Immediate mode.

segment_count: usize

Number of on-disk segments (excludes the in-memory memtable).

node_tombstone_count: usize

Number of node tombstones in the memtable (pending deletes).

edge_tombstone_count: usize

Number of edge tombstones in the memtable (pending deletes).

last_compaction_ms: Option<i64>

Wall-clock timestamp (ms since epoch) of the last completed compaction, or None if no compaction has run since open.

wal_sync_mode: String

The WAL sync mode this database was opened with.

active_memtable_bytes: usize

Estimated bytes in the active (mutable) memtable.

immutable_memtable_bytes: usize

Estimated bytes across all immutable memtables pending flush.

immutable_memtable_count: usize

Number of immutable memtables pending flush.

pending_flush_count: usize

Number of flush operations currently in flight (enqueued to bg worker).

active_wal_generation_id: u64

The WAL generation ID currently being written to.

oldest_retained_wal_generation_id: u64

The oldest WAL generation ID still retained for recovery. Equal to active_wal_generation_id when no immutable memtables are pending.

Trait Implementations
