2.登陆数据库创建表
[root@localhost config]# su - crate
-bash-4.2$ crash --host 192.168.1.129 -U devtest
输入密码


cr> CREATE TABLE doc.myusers (
   id INT primary key,
   name STRING,
   day_joined TIMESTAMP primary key,
   bio STRING INDEX using fulltext,
   address OBJECT (dynamic) AS (
   city STRING,
   country STRING
  )
 ) CLUSTERED INTO 6 shards
 PARTITIONED BY (day_joined)
 WITH (number_of_replicas = 0);
 
3.导入数据
cr> COPY doc.myusers FROM '/home/crate/myuser.json';
COPY OK, 2 rows affected  (0.273 sec)


4.查看数据
cr> select * from doc.myusers;
