|
|
Sets the idle query timeout value for the session, in seconds. Queries that sit idle for longer than the
|
|
timeout value are automatically cancelled. If the system administrator specified the
|
|
<codeph>--idle_query_timeout</codeph> startup option, <codeph>QUERY_TIMEOUT_S</codeph> must be smaller than
|
|
or equal to the <codeph>--idle_query_timeout</codeph> value.

<!-- Don't have a compelling example to show at this time because the 'idle' aspect only applies

when the client is careless and leaves the query open. Can't easily demonstrate in impala-shell.
