Question

使用下面的DDL和配置文件yaml，我使用cassandra-stress为我的表生成随机数据。我为列amount和status获得的结果与期望值不匹配。随机值似乎每个分区绘制一次，而不是每行。

例如，如果cassandra-stress生成具有相同business_date的5行（即一个分区），则amount和status值重复5次，＆＃ 34;下一个＆＃34;当business_date发生变化时会出现随机值。我怎样才能做到这一点，以便为每一行获得amount和status的新抽奖？

示例输出，通知最后两列只在第一列更改后更改值。

表格结构：

CREATE TABLE IF NOT EXISTS record (
business_date date,
region text,
id uuid,
status text,
amount double,
PRIMARY KEY (business_date, region, id)
);

简介YAML：

keyspace: dev
table: record
columnspec:
 - name: business_date
   population: uniform(17800..17845)
 - name: region
   size: fixed(10)
   population: seq(10..16)
   cluster: fixed(7)
 - name: id
   size: fixed(32)
   population: seq(1..10M)
   cluster: fixed(5)
 - name: status
   size: fixed(10)
   population: uniform(1000..1010)
 - name: amount
   population: uniform(500000..10M)
insert:
   partitions: fixed(1)
   select: fixed(1)/35
queries:
   selectall:
    cql: select * from record where business_date = ? and region = ?
    fields : samerow

Cassandra-stress不会为每一行生成随机值
