Cassandra min和max不能处理非分区键

Question

我无法在非分区键上执行标准聚合函数。我试图计算不在整个数据集上的特定分区的最小值和最大值。仍然没有用。

表：

CREATE TABLE testminmax (
   id int,
   user_id text,
   iddate int,
   a double,
   b double,
   c double,
   d double,
   e double,
   f double,
   PRIMARY KEY (id, user_id)
) WITH CLUSTERING ORDER BY (user_id ASC) 

我的cql是select min(a) as min, max(a) as max from testminmax where id =1

我收到以下错误

2017-05-04 17:06:55 [WARNING ] [cassandra.protocol.decode_messag:1087] Server warning: Read 1041 live rows and 100001 tombstone cells for query SELECT * FROM testminmax WHERE id = 1 LIMIT 5000 (see tombstone_warn_threshold)
