logicalSessionTimeoutMinutes property
The time in minutes that a session remains active after its most recent use. Sessions that have not received a new read/write operation from the client or been refreshed with refreshSessions within this threshold are cleared from the cache. State associated with an expired session may be cleaned up by the server at any time.
Null when the server does not support sessions and leaves the field out of its reply, as Amazon DocumentDB 3.6 does.
Implementation
int? logicalSessionTimeoutMinutes;
