Expand description

Represents the state of the storage engine.

Fields§

§memtable: Arc<MemTable>

The current memtable.

§imm_memtables: Vec<Arc<MemTable>>

Immutable memtables, from latest to earliest.

§l0_sstables: Vec<usize>

L0 SSTs, from latest to earliest.

§levels: Vec<(usize, Vec<usize>)>

SsTables sorted by key range; L1 - L_max for leveled compaction, or tiers for tiered compaction.

§sstables: HashMap<usize, Arc<SsTable>>

SST objects.
