> This FLIP proposes two extensions to address these: 
>  * *Physical ID partitioning* for databases that expose a physical row identifier (e.g. Oracle, PostgreSQL), enabling skew-free parallel reads with no user-defined partition column required.
>  * *Boundary query* allows users to define partition boundaries based on actual data distribution, enabling balanced parallel reads for any column type.
