Udp balancing

Hi,

In the default stream/udp/proxy setup, will nginx round robin every
packet
or will it remembers client and send all packets from same client to
same
upstream?

Thanks

The default is round-robin, yes.

You can enable persistent-like behaviour though:

That makes sense for udp (connection less).
What about tcp? I assume when client initiate the connection , nginx
will
pick one upstream (rr) to make a connection and send all subsequent
packets
to the same upstream using the same connection.

Not sure I understand your request.

For tcp nginx balances new connections based on the configured load
balancing discipline (rr by default).

To summarize:
TCP balancing decision is on every new connection.
TCP balancing decision is on every packet since it is connectionless.
