LadybugDB maintainer here.

Couple of corrections:

* LadybugDB has revamped the Kuzu WAL design. It shouldn't be hard to build WAL based replication

* 19ms vs 39us - like the author says these are vastly different systems and the benchmark methodology may not be comparable.

We've mostly focused on query plan optimizations, not so much the micro query operator optimizations.

The 0.20.x end of the month release should have some interesting optimizations.

  * Prepared statements will cache query plans and result vectors. So you don't pay malloc costs
  * SIMD optimizations for filter. More to come in the next release.
