Support for Cassandra CQL database lookup table

[List]

We would like to use the Cassandra database to persist the state of 
abusive IPs which we would block from connecting in one of the 
smtpd_xxx_restrictions clauses.  We have systems that exist in multiple 
data centers and Cassandra works really well for persisting data between 
them, but Postfix does not support Cassandra and specifically the CQL 
language as a lookup table.  Is this planned for any releases in the 
near future?
