Hence, users are forced to specify and execute unnecessary transpose operations. This task aims to resolve this by adding the support for {{colIndexMin}} and {{colIndexMax}}. In detail, this entails (1) adding new tests for these aggregates, (2) extending the language layer by this new builtin function, (3) extending the hop and lop compilation, and (4) adding the necessary runtime support. In separate PRs we further can introduce additional rewrites to remove unnecessary operations in existing scripts. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
