The Vec<RecordBatch> that is returned will contain a single RecordBatch with a single Row and Column, which is the count of rows written. Result<Vec<RecordBatch>> is the return type since under the hood write table calls collect() which collects a stream of RecordBatchs into a Vec. It just so happens this specific plan will only return a single recordbatch with a single value. Since we know InsertExec will only return a single value, we could extract that value and cast to usize. Alternatively, we could expand the documentation to make this more clear. -- This is an automated message from the Apache Git Service.
