Example 1 with Uncompressed

use of org.apache.parquet.format.Uncompressed in project parquet-mr by apache.

the class ParquetMetadataConverter method toBloomFilterHeader.

    BloomFilterAlgorithm algorithm = null;
    BloomFilterHash hashStrategy = null;
    BloomFilterCompression compression = null;

        return new BloomFilterHeader(bloomFilter.getBitsetSize(), algorithm, hashStrategy, compression);
    } else {
