No, sorting by column other than clustering column is not possible

Hello, everyone.



I am using 3.11.0 and I have the following table.



CREATE TABLE summary_5m (

    service_key text,

    hash_key int,

    instance_hash int,

    collected_time timestamp,

    count int,

    PRIMARY KEY ((service_key), hash_key, instance_hash, collected_time)

)





And I can sum count grouping by primary key.



select service_key, hash_key, instance_hash, sum(count) as count_summ 

from apm.ip_summary_5m 

where service_key='ABCED'

group by service_key, hash_key, instance_hash;





But what I want is to get only the top 100 with a high value added.



Like following query is attached … (syntax error, of course)



order by count_sum limit 100;



Anybody have ever solved this problem?



Thank you in advance.
