 def describe_consumer_groups(self, group_ids, group_coordinator_id=None):
 """Describe a set of consumer groups. Any errors are immediately raised. :param group_ids: A list of consumer group IDs. These are typically the group names as strings. :param group_coordinator_id: The node_id of the groups' coordinator broker. If set to None, it will query the cluster for each group to find that group's coordinator. Explicitly specifying this can be useful for avoiding extra network round trips if you already know the group coordinator. This is only useful when all the group_ids have the same coordinator, otherwise it will error. Default: None. :return: A list of group descriptions. For now the group descriptions are the raw results from the DescribeGroupsResponse. Long-term, we plan to change this to return namedtuples as well as decoding the partition assignments. """
