 Sets the amount of data per-peer to be queued by the UDP interconnect on receivers (when
data is received but no space is available to receive it the data will be dropped, and the
transmitter will need to resend it). Increasing the depth from its default value will cause
the system to use more memory; but may increase performance. It is reasonable for this to
be set between 1 and 10. Queries with data skew potentially perform better when this is increased.
Increasing this may radically increase the amount of memory used by the system.

an upper limit of 1000 segment instances - less than that if the query workload involves complex,
multi-slice queries.
