They have their own implementation that is closed source (last time I checked), Photon [1], which is written with a C++ engine.
Databricks' terms prevent(ed?) publishing benchmarks, it would be interesting to see how Comet performs relative to it over time.
Photon comes at a higher cost, so one big advantage of Comet is being able to deploy it on a standard Databricks cluster that doesn't have Photon, at a lower running cost.
