             Summary: Support for variadic parameters list for "in clause" in 
prepared cql query
                 Key: CASSANDRA-4210
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4210
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
    Affects Versions: 1.1.0
         Environment: prepared cql queries
            Reporter: Pierre Chalamet
            Priority: Minor


This query

{code}
select * from Town where key in (?)
{code}

only allows one parameter for '?'.


This means querying for 'Paris' and 'London' can't be executed in one step with 
this prepared statement.

Current workarounds are:
* either execute the prepared query 2 times with 'Paris' then 'London'
* or prepare a new query {{select * from Town where key in (?, ?)}} and bind 
the 2 parameters


Having a support for variadic parameters list with in clause could improve 
performance:
* single hop to get the data
* // fetching server side
