ASF GitHub Bot commented on PARQUET-2257: ----------------------------------------- wgtmac opened a new pull request, #194: URL: https://github.com/apache/parquet-format/pull/194 The specs has only added `bloom_filter_offset` to locate the bloom filter. The reader cannot load the bloom filter in a single shot until it parses the bloom filter header to get the total size. ```thrift struct ColumnMetaData { /** Byte offset from beginning of file to Bloom filter data. **/ 14: optional i64 bloom_filter_offset; } ``` This patch proposes to add an optional bloom_filter_length field to track the size of bloom filter to facilitate I/O scheduling. The specs already do the similar things for column index and offset index. > [Format] Add bloom_filter_length to ColumnMetaData > -------------------------------------------------- > > Key: PARQUET-2257 > URL: https://issues.apache.org/jira/browse/PARQUET-2257 > Project: Parquet > Issue Type: New Feature > Components: parquet-format > Reporter: Gang Wu > Assignee: Gang Wu > Priority: Major > > The specs only has added bloom_filter_offset to locate the bloom filter.
