This is not a feature of export. We are using exp + compress, exp sends dump into a pipe; compress gets data from the pipe and writes the compressed file.

You have to do the other way around when importing.

Depending on size of target table we have anything in between 1 to 4 tablespaces per table. These are generic tablespaces, we assign partitions depending on tablespace utilization/availability.

Just what works for us.
