Release note

We can use geospatial like

create table t1(v1 int, v2 int ,v3 varchar, v4 varchar);
CREATE SINK s1
FROM
    t1 WITH (
    primary_key = 'v3',
    connector = 'redis',
    redis.url= 'redis://127.0.0.1:6379/',
)FORMAT UPSERT ENCODE TEMPLATE
(redis_value_type ='geospatial', 
longitude = 'v1', 
latitude = 'v2', 
member = 'v3',
key_format = 'abcd3:{v4}'
);
insert into t1 values(1.1, 1.1, 'test','test');

then we can get it in redis like

GEOPOS abcd3:test test
------
1) 1) "1.10000044298171997"
   2) "1.10000000482478555"

redis_value_type must be set to string and geospatial, default is string
if redis_value_type is set to string, we must set key_format and value_fomat(Consistent with previous behavior)
if redis_value_type is set to geospatial, we must set key_format, longitude, latitude and member
The meaning of key_format is consistent with redis_value_type = string
The longitude is the column name of rw, the datatype must be float, real or varchar
The latitude is the column name of rw, the datatype must be float, real or varchar
The member is the column name of rw, the datatype must be varchar, and must be primary_key

Perhaps off-the-topic but the trait function is confusing to me: why col_indices need to be passed from outside, while it's stored in self? 😂
