Hello,
Just a heads up here so as to reach a wider audience: I've posted a format addition proposal in https://issues.apache.org/jira/browse/PARQUET-2414 Excerpt: """ This issue proposed to widen the types supported by the BYTE_STREAM_SPLIT. By allowing the BYTE_STREAM_SPLIT on any FIXED_LEN_BYTE_ARRAY column, we can automatically improve compression efficiency on various column types including: half-float data fixed-width decimal data [etc.] """ Feel free to comment here or on the JIRA issue. Regards Antoine.
