Controls
Every button here calls the real engine. Each call records the steps it actually took — read them in the trace below the tree.
Console
Workload
Seeded and deterministic — the same seed replays the same operation stream.
Knobs
Change these under load and watch the amplification tiles move — no setting wins on all three.
Tree
WAL
0 records
durable before any write is acknowledged
memtable
skiplist, sorted in memory → flushes when full
levels
L0 runs overlap (each is one flushed memtable); L1+ are sorted and non-overlapping. Click any run to inspect its bytes.
Operation trace — run an operation to see its steps
Emitted by the engine as it executes, one line per step it actually performed. Nothing here is scripted.
