-------------------------------------------
Summary: CQL3: Allow preparing the consistency level, timestamp
and ttl
Key: CASSANDRA-4450
URL: https://issues.apache.org/jira/browse/CASSANDRA-4450
Project: Cassandra
Issue Type: Improvement
Reporter: Sylvain Lebresne
Priority: Minor
It could be useful to allow the preparation of the consitency level, the
timestamp and the ttl. I.e. to allow:
{noformat}
UPDATE foo SET .. USING CONSISTENCY ? AND TIMESTAMP ? AND TTL ?
{noformat}
A slight concern is that when preparing a statement we return the names of the
prepared variables, but none of timestamp, ttl and consistency are reserved
names currently, so returning those as names could conflict with a column name.
We can either:
* make these reserved identifier (I have to add that I'm not a fan because at
least for "timestamp", I think that's a potentially useful and common column
name).
* use some specific special character to indicate those are not column names,
like returning "[timestamp]", "[ttl]", "[consistency]".
