for details of the required configuration. Search for {{bloom.filter}}.
> Support writing bloom filters in Parquet
> ----------------------------------------
>
> Key: HIVE-24831
> URL: https://issues.apache.org/jira/browse/HIVE-24831
> Project: Hive
> Issue Type: New Feature
> Components: Parquet
> Reporter: Csaba Ringhofer
> Priority: Major
>
> Parquet-mr 1.12.0 will add support for reading and writing Bloom filters.
> Reading doesn't need any action from Hive side, as it will be applied
> automatically if there is an Eq predicate on a column and the file contains a
> bloom filter.
> Writing needs some configuration, as Parquet-mr doesn't write bloom filters
> by default.
> Similar table properties could be used as in ORC, e.g.
> 'orc.bloom.filter.columns' to set the columns where Parquet-mr should write
> bloom filters. The same table property could be used by both Hive and Impala
> for the same purpose.
