@kou, I think there are some inaccuracies in the Statistics Schema specification. Let me explain: 1-As you pointed out [here](https://github.com/apache/arrow/issues/45560#issuecomment-2687096141), ARROW:row_count:approximate is not applicable to `arrow::RecordBatch`. However, the [specification](https://arrow.apache.org/docs/dev/format/StatisticsSchema.html#standard-statistics) currently states that it is required: _The number of rows in the target table, record batch or array. (approximate)_ 2- The specification does not include any examples involving tables. 3- There's no mention of `ChunkedArray`. Is that because `ChunkedArray` is not consistently supported across all Arrow implementations? -- This is an automated message from the Apache Git Service.
