Is this scan mask some sort of bitmap alongside an Arrow vector? or it is associated with a Parquet column chunk. You can also check out this paper: [Filter Representation in Vectorized Query Execution](https://dl.acm.org/doi/abs/10.1145/3465998.3466009), to compare that against a selection vector based approach. AFAIK the latter may yield better performance due to no branching cost. -- This is an automated message from the Apache Git Service.
