[jira] [Updated] (ASTERIXDB-2399) Rename COLL_* aggregate functions
into STRICT_*
[ https://issues.apache.org/jira/browse/ASTERIXDB-2399?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Till updated ASTERIXDB-2399:
----------------------------
Description:
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.
