当redis表作为sink时,需要配置connector.command
CREATE TABLE dim_table (
user_id VARCHAR,
age varchar
) WITH (
'connector' = 'redis',
'host' = '10.122.173.131',
'port' = '6379',
'mode' = 'single',
'db.index' = '0',
'password' = 'xxx',
'lookup.cache.type' = 'all',
'lookup.cache.ttl' = '3000',
'primary.key' = 'user_id'
CREATE TABLE sink (
item_id VARCHAR,
item_type varchar
) WITH (
'connector' = 'redis',
'host' = '10.122.173.131',
'port' = '6379',
'mode' = 'single',
'db.index' = '0',
'password' = 'xxx',
'lookup.cache.type' = 'all',
'lookup.cache.ttl' = '3000',
'primary.key' = 'item_id',
'connector.command' = 'SET'
);
INSERT INTO pvuvage_sink
select d.ts as dt, d.age, count(*) as pv, count(distinct d.user_id) as uv
from (
SELECT
u.ts,
cast(w.age as int) as age,
u.user_id,
u.behavior
FROM (select user_id,item_id,category_id,behavior,ts,PROCTIME() as proc from user_log) as u
join dim_table for system_time as of u.proc as w
on u.user_id = w.user_id
where w.age > 10
) as d
GROUP BY d.ts, d.age;
set 'SADD.db.index' ='4';
set 'SADD.primary.key' = 'item_id';
使用metahub方式的redis作为维表时,redis命令使用GET,关联键名是k,值名是v
INSERT INTO sloth_redis_test.mem.`HSET`
select d.ts as item_id, cast(d.age as string) as item_type, cast(count(*) as string) as `redis.value`
from (
SELECT
u.ts,
cast(w.v as int) as age,
u.user_id,
u.behavior
FROM (select user_id,item_id,category_id,behavior,ts,PROCTIME() as proc from user_log) as u
join sloth_redis_test.`default`.`GET` for system_time as of u.proc as w
on u.user_id = w.k
where w.v > 10
) as d
GROUP BY d.ts, d.age;

| redis 集群模式 | 选填;默认值为single;支持single, sentinel, cluster 3种集群模式;cluster及sentinel模式中,host用逗号分隔,如host,host,host...;sentinel模式需要设置master | master | master 地址 | 当 mode = 'sentinel' 时才需要 | password | redis 密码 | 当 mode 为 single、sentinel 可选填 | db.index | 对应 redis 的 db | 选填;默认为0; | connector.lookup.cache.type | 选填,默认'none',支持:'all', 'lru', 'none' | connector.lookup.cache.max-rows | 最大缓存条数 ,默认10000条, type 为 lru 时有效 | connector.lookup.cache.ttl | 当选择'lru'表示缓存失效时间,默认不过期;当选择'all'表示 reload 间隔时间 | 选填,默认不 reload | connector.lookup.max-retries | dim 表获取失败时最大重试次数 | 选填,默认3次 |
