Driver	Cassandra
`cass_int32_t`	`int`
`cass_int64_t`	`bigint`, `counter`, `timestamp`
`cass_float_t`	`float`
`cass_double_t`	`double`
`cass_boot_t`	`boolean`
`const char*`	`ascii`, `text`, `varchar`
`const cass_byte_t*`	`blob`, `varint`
`CassUuid`	`uuid`, `timeuuid`
`CassInet`	`inet`
`const cass_byte_t* (varint) and a cass_int32_t (scale)`	`decimal`
`CassCollection`	`list`, `map`, `set`

Cassandra 2.0+ is required for parameterized queries, prepared statements, paging, and batches. Cassandra 1.2 does NOT support these features.
