Sets the amount of data per-peer to be queued by the UDP interconnect on senders. Increasing the depth from its default value will cause the system to use more memory; but may increase performance. Reasonable values for this parameter are between 1 and 4. Increasing the value might radically increase the amount of memory used by the system.

This parameter is used only when gp_interconnect_type is set to UDPIFC.
