Hello, Sorry for late response.
If you will see first message of this third, you will understand that initially I had used same schema. But collocation were not working. By the way, now I have again inserted sample data (sent in previous messages) as per your suggestion . 1000 cities and 3 countries. 1st Country = 500 cities 2nd Country = 300 cities 3rd Country = 200 cities CREATE TABLE Country ( country_id INT(10), country_name CHAR(30), Continent CHAR(30), PRIMARY KEY (country_id) ) WITH "template=partitioned, backups=1"; CREATE TABLE City ( city_id INT(15), country_id INT(10), city_name CHAR(50), Dist CHAR(20), PRIMARY KEY (city_id,country_id) ) WITH "template=partitioned, backups=1, affinityKey=country_id"; output : select count(*) from City c join Country cc on cc.country_id = c.country_id ; => Count = 1000 select count(*) from City c join Country cc on cc.country_id != c.country_id; => Count = 800 Do you think data is collocated ? So what are the logical explanation for count=1000 for first query and count = 800 for second query. Thanks, Nilesh -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
