}
A ReadConcern defines a MongoDB read concern, which allows you to control the consistency and isolation properties of the data read from replica sets and replica set shards.
For more information about MongoDB read concerns, see https://www.mongodb.com/docs/manual/reference/read-concern/
func Available ¶
func Available() *ReadConcern
Available returns a ReadConcern that requests data from an instance with no guarantee that the data has been written to a majority of the replica set members (i.e. may be rolled back).
For more information about read concern "available", see https://www.mongodb.com/docs/manual/reference/read-concern-available/
func Linearizable ¶
func Linearizable() *ReadConcern
Linearizable returns a ReadConcern that requests data that reflects all successful majority-acknowledged writes that completed prior to the start of the read operation.

func Local ¶
func Local() *ReadConcern
Local returns a ReadConcern that requests data from the instance with no guarantee that the data has been written to a majority of the replica set members (i.e. may be rolled back).

func Majority ¶
func Majority() *ReadConcern
Majority returns a ReadConcern that requests data that has been acknowledged by a majority of the replica set members (i.e. the documents read are durable and guaranteed not to roll back).
For more information about read concern "majority", see https://www.mongodb.com/docs/manual/reference/read-concern-majority/
func Snapshot ¶
func Snapshot() *ReadConcern
Snapshot returns a ReadConcern that requests majority-committed data as it appears across shards from a specific single point in time in the recent past.
