MySQL :: MySQL 8.0 Reference Manual :: 5.1.8 Server System Variables https://dev.mysql.com/doc/refman/8.0/en/server-system-variables.html#sysvar_interactive_timeout

 

interactive_timeout

PropertyValue
Command-Line Format --interactive-timeout=#
System Variable interactive_timeout
Scope Global, Session
Dynamic Yes
SET_VAR Hint Applies No
Type Integer
Default Value 28800
Minimum Value 1

The number of seconds the server waits for activity on an interactive connection before closing it. An interactive client is defined as a client that uses theCLIENT_INTERACTIVE option to mysql_real_connect(). See also wait_timeout.

 

wait_timeout

PropertyValue
Command-Line Format --wait-timeout=#
System Variable wait_timeout
Scope Global, Session
Dynamic Yes
SET_VAR Hint Applies No
Type Integer
Default Value 28800

Maximum Value (Windows) 2147483
 

The number of seconds the server waits for activity on a noninteractive connection before closing it.

On thread startup, the session wait_timeout value is initialized from the global wait_timeout value or from the global interactive_timeout value, depending on the type of client (as defined by the CLIENT_INTERACTIVE connect option to mysql_real_connect()). See also interactive_timeout.
