new sink:

CREATE TABLE IF NOT EXISTS movies (
    year integer,
    title varchar,
    description varchar,
    primary key (year, title)
);

CREATE SINK
  dyn_sink
FROM
  movies
WITH
(
  connector = 'dynamodb',
  table = 'Movies',
  primary_key = 'year,title',
  endpoint = 'http://localhost:8000',
  region = 'us',
  access_key = 'ac',
  secret_key = 'sk'
);

• struct may be better mapped to DynamoDB Map
• jsonb can be mapped as string for now, and latter extended to a dynamic recursive one similar to #11699. It is your call whether the latter dynamic one shall be the default here instead. Just bringing the alternative option to attention.

[jetjinser]

• I'm not sure, the struct here must be named, since in create sink?
• Does this mean providing an TimestampHandlingMode-like option for jsonb format to DynamoDB sink?

[neverchanje]

You can consider struct as a list of named key values pairs, right?

struct <
  id varchar,
  name varchar
>

Map<String, Value> {
  "id": "123",
  "name": "jinser"
}

Yes, I think the current implementation is like this

Both are fine, up to you 😃

Is it safe to use take here?

There seems to be no problem, is there anything to worry about
