[Gang Wu](https://issues.apache.org/jira/browse/PARQUET-2222?#comment-17746755) / @wgtmac: I just revisited this issue. Let me summarize the current state in different implementations for BOOLEAN type: - parquet-mr: - write: Always PLAIN for v1 and RLE for v2. - read: Use the actual encoding to create decoder, so both encodings are supported for any data page version. - arrow-rs: - write: By default PLAIN for v1 and RLE for v2, but can apply RLE for v1 as well. - read: Use the actual encoding to create decoder. - parquet-cpp: - write: By default PLAIN for v1 and v2 pages, but both page versions can apply RLE. - read: Use the actual encoding to create decoder. -- This is an automated message from the Apache Git Service.
