Fields

max_opened: usize

max_opened is the maximum number of opened sessions allowed by the session pool. If the client tries to open a session and there are already max_opened sessions, it will block until one becomes available or the context passed to the client method is canceled or times out.

min_opened: usize

min_opened is the minimum number of opened sessions that the session pool tries to maintain. Session pool won’t continue to expire sessions if number of opened connections drops below min_opened. However, if a session is found to be broken, it will still be evicted from the session pool, therefore it is posssible that the number of opened sessions drops below min_opened.

max_idle: usize

max_idle is the maximum number of idle sessions, pool is allowed to keep.

idle_timeout: Duration

idle_timeout is the wait time before discarding an idle session. Sessions older than this value since they were last used will be discarded. However, if the number of sessions is less than or equal to min_opened, it will not be discarded.

session_alive_trust_duration: Duration

session_get_timeout: Duration

session_get_timeout is the maximum value of the waiting time that occurs when retrieving from the connection pool when there is no idle session.

refresh_interval: Duration

refresh_interval is the interval of cleanup and health check functions.
