Fixes a regression introduced in
9e88b60ef5, which broke the lookup for
prefetched values of lists when a clustering key is specified.
This is the code that was removed from some list operations:
std::experimental::optional<clustering_key> row_key;
if (!column.is_static()) {
row_key = clustering_key::from_clustering_prefix(*params._schema, prefix);
}
...
auto&& existing_list = params.get_prefetched_list(m.key().view(), row_key, column);
Put it back, in the form of common code in the update_parameters class.
Fixes#3703
