jshmchenxi opened a new pull request #2582: URL: https://github.com/apache/iceberg/pull/2582
For #2391, add Parquet BloomFilter support to Iceberg. Upgrade Parquet version to 1.12.0 and add ParquetBloomRowGroupFilter similar to ParquetDictionaryRowGroupFilter. ExpressionVisitor is implemented with refer to [org.apache.parquet.filter2.bloomfilterlevel.BloomFilterImpl](https://github.com/apache/parquet-mr/blob/apache-parquet-1.12.0/parquet-hadoop/src/main/java/org/apache/parquet/filter2/bloomfilterlevel/BloomFilterImpl.java). BloomFilter is helpful only with eq() and in() expression. It can not help filtering rows with other expressions like gt() or notEq(). Add 3 new properties to TableProperties. The definition is similar to #parquet-mr - write.parquet.bloom-filter-enabled - write.parquet.bloom-filter-max-bytes - write.parquet.bloom-filter-expected-ndv -- This is an automated message from the Apache Git Service.
