How to visualize operators execution in flink-sql job graph if chaining is in action or not

I have flink-sql application that just perform simple simple insert into enrich table by joining multiple tables.

    create table T1 (...) WITH ( 'connector' = 'upsert-kafka','topic' = 'T1', ...)
    create table T2 (...) WITH ( 'connector' = 'upsert-kafka','topic' = 'T2', ...)
    create table enrich (...) WITH ( 'connector' = 'upsert-kafka','topic' = 'enrich', ...)


CREATE TEMPORARY VIEW distinct_t1 AS
SELECT *
FROM (SELECT *,
ROW_NUMBER() OVER (PARTITION BY id ORDER BY change_date desc) AS rownum
FROM T1)
WHERE rownum = 1;


CREATE TEMPORARY VIEW distinct_t2 AS
SELECT *
FROM (SELECT *,
ROW_NUMBER() OVER (PARTITION BY id ORDER BY change_date desc) AS rownum
FROM T2)
WHERE rownum = 1;

    insert into enrich 
    select ... from distinct_t1 t1 inner join distinct_t2 t2 ... t2.t1_id = t1.id and t2.client_id=t1.client_id

Note:

1. Kafka partitions are 8 on raw topics and parallelism is set 8 on
2. Max Parallelism is default (i believe that is 128 lower bound)
3. TaskSlot=1 and total 8 TaskManagers processing are running

Question1: Based on above configuration, I am visualizing my job graph (including source, rank, join and sink operator running on TM1 reading from partition0 something like this.. am i right??

1. TM1

   • T1-partition[0] - source_operator[0] -> rank_operator[0] -> Join
   • T2-partition[0] - source_operator[0] -> rank_operator[0] ->. > Sink Operator

2. TM2

   • T1-partition1 - source_operator1 -> rank_operator1 -> Join
   • T2-partition1 - source_operator1 -> rank_operator1 ->. > Sink Operator ...

3. TM8

   • T1-partition[7] - source_operator[7] -> rank_operator[7] -> Join
   • T2-partition[7] - source_operator[7] -> rank_operator[7] ->. > Sink Operator

Question2: how can i verify if my operators are chained or not ? or any configuration that i have to set in environment

Question3: In case if these operators are not chained as i am visualizing then how do i verify what operators are running where ??

Edit: I am using flink 1.17.1 and here is the job graph that just shows the operator but not other info like if they are chained or not

If you have access to the Flink Web UI, this information is presented there in an easy-to-understand way. This is normally running on the job manager at port 8081.

Each blue box in the diagram is a task, or in other words, an operator chain. The operators shown together within the same blue box are chained. Nothing else is.
