> We need to document GROUP_CONCAT aggregate function.
> # Explain users that {{DISTINCT}} and {{ORDER BY}} is supported only for collocated {{GROUP
BY}};
> # String concatenation expressions are separated by {{||}} (not by comma as described
at the [draft|https://dash.readme.io/project/apacheignite-sql/v2.6/docs/group_concat]); e.g.:
{{GROUP_CONCAT(valueId || '=' || value SEPARATOR '; ')}}
