---------------------------------
Summary: Flink SQL to support COLLECT_LIST (was: Flink SQL to support
COLLECTLIST)
> Flink SQL to support COLLECT_LIST
> ---------------------------------
>
> Key: FLINK-33765
> URL: https://issues.apache.org/jira/browse/FLINK-33765
> Project: Flink
> Issue Type: Improvement
> Components: API / DataSet
> Reporter: Zhenzhong Xu
> Priority: Major
>
> Flink SQL currently supports COLLECT, which returns a multiset, however,
> given support for casting from multiset to other types (especially
> array/list) is *very* limited, see
> [here,|https://github.com/apache/flink/blob/master/docs/content/docs/dev/table/types.md#casting]
> this is creating lots of headaches for ease of use.
> Can we support COLLECT_LIST as a built-in system function?
