> my point is that even in the single row group case maybe it should be inexact? if the write used a bloom filter as discussed above it could be 1% off (in either direction i believe) We have been working so far under the assumption that `distinct_count` is exact in Parquet (see https://github.com/apache/arrow-rs/issues/8608#issuecomment-4041317278 from @alamb), has this changed in the meantime? If so, I agree that we should consume it as `Inexact` everywhere, as we have rules relying on that for correctness as @Rich-T-kid has noticed. -- This is an automated message from the Apache Git Service.
