Return all rows from Druid GroupBy query

[ishan8]

Is there a way to execute a Druid GroupBy query where we get back all rows? Looks like there's currently a defaultMaximumMaxRows value.

maha/core/src/main/scala/com/yahoo/maha/core/query/druid/DruidQueryGenerator.scala

Line 158 in d6b48f2

val defaultMaximumMaxRows: Int = 5000

Last I checked Druid had a limit on the number of rows that can be sent from historical to broker and it didn't support pagination.

You can pass in your own value, see register method:

maha/core/src/main/scala/com/yahoo/maha/core/query/druid/DruidQueryGenerator.scala

Line 166 in d6b48f2

def register(queryGeneratorRegistry: QueryGeneratorRegistry

in the case of returning large rows, you might want to use OffHeapRowList #675
