Hi All ,

I am using Java scroll API to fetch data from an index . Is it possible to use CompositeAggregationBuilder along with scroll api and get aggregation resultset in batches of 10000 from elastic . If so , please help me how to set the size of searchsourcebuilder and CompositeAggregationBuilder size.

Thanks In Advance,  
Vands
