组合键和计数器。我可以创建柱族，但不能填充它

Question

我知道柜台家族可以有任何类型的钥匙。不支持组合键吗？

 cqlsh:goh_master> create columnfamily balance (kind ascii, corporation_id ascii, amount  counter, primary key ( kind,corporation_id) ) with compact storage;
 cqlsh:goh_master> insert into balance(kind,corporation_id,amount) values ('c',103,123456789);
 Bad Request: invalid operation for commutative columnfamily balance

 cqlsh:goh_master> insert into balance(kind,corporation_id,amount) values ('c',103,123456789);

Answer 1

多亏了this answer我自己解决了这个问题。你不能插入计数器，也不能只是设置。必须始终使用set counter =counter +n语法：

cqlsh:goh_master> update balance set amount=amount+12 where kind='c' and corporation_id = 103;

像个护身符一样工作
