ccaominh commented on issue #9168: "assumeGrouped" behaves differently in 
native batch and hadoop tasks
URL: https://github.com/apache/druid/issues/9168#issuecomment-576847712
 
 
   When `assumeGrouped` is `true`, range partitioning for native batch does not 
have to hash dimension values for bloom filter inserts/tests. There's also some 
reduction in memory usage as the bloom filter does not need to be created. Both 
of these should help `PartialDimensionDistributionTask` run slightly faster 
than when `assumeGrouped` is `false`.
