Subject [jira] [Commented] (CASSANDRA-12051) JSON does not take functions
Date Thu, 07 Jul 2016 16:12:10 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-12051?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15366334#comment-15366334
] 

Tyler Hobbs commented on CASSANDRA-12051:
-----------------------------------------

Ah, good point.  I forgot that we accepted the string literal {{now}} for timestamp values.
 This isn't technically a function call (in CQL terms), so other function names will not work.
