Jeremiah Jordan commented on CASSANDRA-7726:
--------------------------------------------

If we provide the safe way, then we probably don't need to.  We can close it as a dup of this.

> Inorder to ease migration from CqlPagingRecordReader to CqlRecordReader, it would be
helpful if CRR input_cql defaulted to a select statement that would mirror the behavior of
CPRR.
> For example for a give table with partition key `((x,y,z),c1,c2)`
> It would automatically generate
> {code}
> input_cql = SELECT * FROM ks.tab WHERE token(x,y,z) > ? AND token (x,y,z) <= ?

> {code}
