### Is your feature request related to a problem or challenge? for example, in https://github.com/lakehq/sail/blob/main/crates/sail-plan/src/extension/function/math/randn.rs it seems that every record batch will have same init seed and same random result. ### Describe the solution you'd like add partition & record_batch_index into evalutate method arguments. e.g. ```rust pub trait PhysicalExpr { fn evaluate(&self, batch: &RecordBatch, partiton: usize, record_batch_index: usize) -> Result<ColumnarValue>; } ``` then we get different seed for different record batch. in spark, seeds are different for different partitions. ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
