Summary: Consider adding BloomFilterHeader to ColumnMetaData Key: PARQUET-1981 URL: https://issues.apache.org/jira/browse/PARQUET-1981 Project: Parquet Issue Type: Improvement Components: parquet-format Reporter: Csaba Ringhofer Currently ColumnMetaData only contains bloom_filter_offset, which points to BloomFilterHeader followed by the bloom filter data. This solution is not optimal during reading, as two IO reads are needed once we know bloom_filter_offset - one to read the header, which contains the size of the bloom filter, then another to read the actual bloom filter to a buffer. Having the size near bloom_filter_offset would allow to do this in a single read. Having algorithm/hash/compression could be also useful by allowing skipping the read of the bloom filter if one of those parameters is not supported. -- This message was sent by Atlassian Jira (v8.3.4#803005)
