Is there an aggregation function for Apache Ignite similar to ARRAY_AGG? I'm trying to pass multiple values to a custom function after grouping, but I was not able to do it for Apache Ignite query ( same query in posgresql was done with ARRAY_AGG and Group by)

Take a look at GROUP_CONTACT
Also check out custom sql functions. These might help your use case.

  • I'm not sure why I can't pass multiple values to GROUP_CONCAT / custom SQL function. If I have 3 rows, I group by row 1 and 2 it will say I need to group by row 3 as well if I want to pass value of row3 to the function. If I group by row 3 , I will pass just 1 value, instead of all values for row 2 – Razvan Dec 17 '21 at 08:10
