2.登陆数据库创建表
[root@localhost config]# su - crate

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,

)
) 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
