When I check for price tags for MySQL, I see a clause called "1-4 socket server" or "5+ Socket Server".. what does this mean?
"Socket" in generic term means Inter Communication Protocol. For MySQL, a socket unix file helps to communicate between MySQL server and MySQL client within local server, and there is only one as far as I know per MySQL server instance.
Please correct me if my understanding is wrong. Kindly shed some light what is meant by 4, 5+ sockets as I see cost increases as socket numbers rises. Also, what are the advantages of the higher sockets?
