![automatic_timestamp option [compatibility]](gif/backward.gif)
Limits impact on the performance of connections other than the current connection.
On, Off
Off
Can be set for an individual connection or for the PUBLIC group. Takes effect immediately.
If you set this option temporarily, that setting applies to the current connection only. Different connections under the same user ID can have different settings for this option.
Intra-query parallelism is not used for connections with background_priority set to on. See Parallelism during query execution.
When set to On, it requests that the current connection have minimal impact on the performance of other connections. This option allows tasks for which responsiveness is critical to coexist with other tasks for which performance is not as important.
