When I connect to a mysql server via a client, it seems to create two new TCP connections each time, for example doing:

$ netstat -a |grep mysql
# tcp4       0      0  lmy.att.64710 ec2-54-00.mysql ESTABLISHED
# tcp4       0      0  lmy.att.64705 ec2-54-00.mysql ESTABLISHED

What does it need the two TCP connections for, and why wouldn't it just create a single one?

You didn't specify what the client is, so all anyone can give you is wild guesses. – Michael Hampton Nov 06 '20 at 23:37
@MichaelHampton I tried using MySQL workbench and Sequel Pro and they both opened two. – David542 Nov 06 '20 at 23:43
What version of mysql? – Mark Scheck Nov 07 '20 at 09:11
