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..."}}]
   ```
