I am reading clickhouse mutation code. In StorageMergeTree->selectPartsToMutate() function, there is a check 
`if (current_ast_elements + commands_size >= max_ast_elements)
                break;`

I think if there are many mutations then the check result will be true, so that it will skip the remaining mutations.
But the new part's mutation is set to the last one in mutation map, and it does not apply the remaining mutations actually.
`new_part_info.mutation = current_mutations_by_version.rbegin()->first;`

Then the new part will miss the remaining mutations in future mutation job.

I think it's wrong here. Am I right?

If it is right, I will submit a PR 

if (!inactive_replicas.empty() && inactive_replicas.count(replica))
            break;
        
        
        if (!getZooKeeper()->exists(fs::path(zookeeper_path) / "mutations" / mutation_id))
        {
            throw Exception(ErrorCodes::UNFINISHED, "Mutation {} was killed, manually removed or table was dropped", mutation_id);
        }
        if (partial_shutdown_called)
            throw Exception("Mutation is not finished because table shutdown was called. It will be done after table restart.",
                ErrorCodes::UNFINISHED);
        
        if (!inactive_replicas.empty() && inactive_replicas.count(replica))
            continue;
        
        std::set<String> mutation_ids;
        mutation_ids.insert(mutation_id);
        
        
        auto mutation_status = queue.getIncompleteMutationsStatus(mutation_id, &mutation_ids);
        checkMutationStatus(mutation_status, mutation_ids);
    }
    if (!inactive_replicas.empty())
    {
        throw Exception(ErrorCodes::UNFINISHED,
                        "Mutation is not finished because some replicas are inactive right now: {}. Mutation will be done asynchronously",
                        boost::algorithm::join(inactive_replicas, ", "));
    }
}
