Hi all, In previous version, we don't guarantee the result order for last query which means you may get different order for the same last query sql. Absolutely, the result set will be same.
The reason for that is to achieve better performance of last query. Without taking ordering into consideration, last query will have lower latency. However, if so, we may fail in current cluster IT, because it will compare result by line from different datanodes. So, I made this discussion about whether we should make last query defaultly order by timeseries which will guarantee the result order. Definitely, it will be in cost of loss of performance. Or, we keep unchanged and add order by timeseries clause for each last query sql in IT. Best, --------------- Yuan Tian
