### Describe the bug Related to - https://github.com/apache/parquet-format/pull/591 on https://github.com/apache/parquet-format/pull/591#issuecomment-4816035024, @HuaHuaY reports > I found that arrow-rs already allows to omit value array. https://github.com/apache/arrow-rs/blob/7616e10f12894232eacb807993e55427a067d061/parquet-variant-compute/src/variant_array.rs#L858 Specifically, according to this report when a shredded variant value array contains only nulls, then the arrow-rs writer omits writing it. According to the discussion https://github.com/apache/parquet-format/pull/591 the spac *requires* writiing a value field (even though there are examples that don't have the value field) ### To Reproduce _No response_ ### Expected behavior Not sure ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
