A document that specifies the write concern for the replica set.
The replica set will use this write concern only when write operations or
getLastErrorspecify no other write concern.
Does the “settings.getLastErrorDefaults” setting change the Write Conern option by default for all write queries for mongodb server?
And what is the value that has changed like this, and if the Write Conern applied to the query comes in? Are you saying that if the w option exists in operation, you ignore the setting value of settings.getLastErrorDefaults?
