-------------------------------------
Summary: Add new CQL function maxWritetime
Key: CASSANDRA-17425
URL: https://issues.apache.org/jira/browse/CASSANDRA-17425
Project: Cassandra
Issue Type: Improvement
Components: CQL/Syntax
Reporter: Yifan Cai
Assignee: Yifan Cai
The function "writetime" does not support multi-cell types, e.g. collections
and UDT. It would be useful to enable querying the latest modified timestamp of
a column value.
I'd like to propose to add a new function named "maxWritetime", which returns
the largest timestamp amongst the cells. When being applied to the single cell
types, it returns the same result as "writetime".
