Thanks @coderfender this would also need to be tested by sql tests trying to cover as much edge cases as possible. Mark joins are pretty recently added in DF and might require extra testing

Thanks @coderfender. The posted benchmarks show that this would be a performance regression compared to Spark? Did performance improve since those were posted? |

Apparently sooner or later we would need to use DF mark joins, they can be disabled by default and we can improve them in background |
