> Key: ASTERIXDB-2399
> URL: https://issues.apache.org/jira/browse/ASTERIXDB-2399
> Project: Apache AsterixDB
> Issue Type: Bug
> Components: *DB - AsterixDB, DOC - Documentation, FUN - Functions,
> SQL - Translator SQL++
> Affects Versions: 0.9.3
> Reporter: Till
> Assignee: Till
> Priority: Major
> Fix For: 0.9.4
>
>
> There are 2 kinds of aggregation functions in SQL++ right now:
> # those with the prefix ARRAY_ (which share SQL's behavior or ignoring NULL)
> and
> # those with the prefix COLL_ (which return NULL, if one of the values is
> NULL).
> To reduce the confusion about which functions implement a strict NULL
> handling we should rename to COLL_ functions to use the prefix STRICT_
> instead.
