clintropolis opened a new pull request #6397: Adds bloom filter aggregator to 'druid-bloom-filters' extension URL: https://github.com/apache/incubator-druid/pull/6397 This PR, building on top of the work introduced in #6222, extends `druid-bloom-filters` with an aggregator, allowing bloom filters to be computed from query results which can then be used as input to `bloom` filters in subsequent queries. example query: ```json { "queryType": "timeseries", "dataSource": "wikiticker", "intervals": [ "2015-09-12T00:00:00.000/2015-09-13T00:00:00.000" ], "granularity": "day", "aggregations": [ { "type": "bloom", "name": "userBloom", "maxNumEntries": 100000, "field": { "type":"default", "dimension":"user", "outputType": "STRING" } } ] } ``` example results: ```json [{"timestamp":"2015-09-12T00:00:00.000Z","result":{"userBloom":"BAAAJhAAAA..."}}] ```
