Durability Bench

In-tab microbench: log-append vs scattered row vs cache-aside.

TypedArray sequential vs random vs Map eviction. Winner is this heap, not a kernel.

Renamed from “Veloce vs Redis/Postgres leaderboard farm”. JS heap microbench.

winner

Log-structured append (Veloce analogue)

0.08 ms

Sequential write into a typed array. Closest analogue of an append-only intent log in this tab.

row

Scattered row write

0.73 ms

Pseudo-random index writes. Stand-in for a row store under churn — not a vendor database.

cache

Cache-aside Map

134.2 ms

JS Map with FIFO eviction. Stand-in for a cache — not a named cache product.
