Hi Devs,
I am trying to implement Array_Agg(
https://cloud.google.com/bigquery/docs/reference/standard-sql/aggregate_functions#array_agg
) for Beam SQL ZetaSQL dialect, as CombineFn.
Rough Pseudocode:
* public static class ArrayAgg extends CombineFn<T, T[], T[]> { //todo }*
But then I came to know we cannot use generics for UDAFs as per
https://issues.apache.org/jira/browse/BEAM-11059, is there any alternative?
Thanks!
