* array_concat_agg and array_agg support for array inputs changes: * added array_concat_agg to aggregate arrays into a single array * added array_agg support for array inputs to make nested array * added 'shouldAggregateNullInputs' and 'shouldCombineAggregateNullInputs' to fix a correctness issue with STRING_AGG and ARRAY_AGG when merging results, with dual purpose of being an optimization for aggregating * fix test * tie capabilities type to legacy mode flag about coercing arrays to strings * oops * better javadoc |
