The MongoDB\Driver\WriteConcern class

(mongodb >=1.0.0)

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.

final class MongoDB\Driver\WriteConcern implements MongoDB\BSON\Serializable, Serializable {

/* Sabitler */

const string MAJORITY = "majority";

/* Özellikler */

public readonly string|int|null $w;

public readonly ?bool $j;

public readonly int $wtimeout;

/* Yöntemler */

final public function bsonSerialize(): stdClass

final public function __construct(string|int $w, ?int $wtimeout = null, ?bool $journal = null)

final public function getJournal(): ?bool

final public function getW(): string|int|null

final public function getWtimeout(): int

final public function isDefault(): bool

}

w: The write concern value (integer number of nodes, the string "majority", or a custom write concern tag name), or null if not set.
j: Whether write operations must be committed to the journal before acknowledged, or null if not specified.
wtimeout: The timeout in milliseconds to wait for write concern acknowledgement. A value of 0 means to wait indefinitely.

MongoDB\Driver\WriteConcern::MAJORITY: Majority of all the members in the set; arbiters, non-voting members, passive members, hidden members and delayed members are all included in the definition of majority write concern.
