Oh I see. I didn't check the predicate implementation. I just only saw that the [Java counterpart](https://github.com/apache/orc/blob/master/java/core/src/java/org/apache/orc/impl/writer/BinaryTreeWriter.java#L95) updates the filter, and I thought it could be problematic initialising but not updating it on the C++ side. But now I checked Trino as another reference, where it seems neither the reader expects Bloom filter for a binary column (just like the implementations here), nor the writer creates Bloom filter for binary statistics. I guess there aren't many valid use cases for it. Should I close this with the related issue? -- This is an automated message from the Apache Git Service.
