The MongoDB\Driver\WriteConcern class

Giriş

MongoDB\Driver\WriteConcern describes the level of acknowledgement requested from MongoDB for write operations to a standalone mongod or to replica sets or to sharded clusters. In sharded clusters, mongos instances will pass the write concern on to the shards.
