-----------------------------------
Hi [~jark], as you say, I understand we should do as follows:
# Firstly, TtlListState#IteratorWithCleanup support remove method which can
remove the element;
# Secondly, in StateListView#remove method we first get the iterator from
state, and remove the value, then we add remaining element in it to new
ArrayList, and update list to state.
Do I understand correctly?

> Affects Versions: 1.12.0
> Reporter: dalongliu
> Priority: Critical

> In Flink-17096 , we are using TTL State refactor group Agg function state
> expiration implement instead of Timer way. However, there’s a slight problem
> which AggregateITCase#testListAggWithRetraction test failed because of
> *IteratorWithCleanup* didn't support remove element, so maybe we need to
> support {{remove}} for {{TtlListState#IteratorWithCleanup.}}
